MACE Flo-series instruments utilise the Doppler Effect to measure velocity of
stream flows.
The Doppler Effect (after C. J. Doppler 1803-53) is defined as, “the apparent
change in the frequency of sound or electromagnetic radiation due to
relative motion between the source and the observer” (Uvarov & Isaacs
(1986). Dictionary of Science).
The MACE Flo-Series instruments transmit an ultrasonic (sound) wave into
the flow. This sound wave is reflected by acoustically reflective particles
(e.g. air bubbles, suspended solids) and the instrument detects the reflected
frequencies. The difference between the transmitted frequency and the
received frequencies is directly proportional to the velocity of the
stream flow.

In full or partially full pipes, the velocity of the stream flow varies markedly
across the cross-section of the pipe. Typically, velocity is zero along the wall
of the pipe and increases to a maximum at or about the centre of the pipe.
MACE Flo-series instruments receive reflected frequencies from particles
moving at these different velocities. The greater the area of flow moving at
a particular velocity, the greater the number of reflections with the
respective frequency shift. The average velocity of the stream is therefore
calculated by averaging those frequency reflections received across the
whole stream profile.

2.0 Warnings
3.0 Site selection
2.1 Intrinsic Safety
When selecting a suitable site to measure flow and mount the instrument,
you must consider the following:
The FloPro Series 3 is NOT an intrinsically safe instrument and should not be
installed in hazardous (explosive) environments. Should an intrinsically safe
instrument be required, MACE can offer other instruments with this approval
level.
2.2 Floods
MACE recommends that the FloPro Series 3 electronics module be mounted
above known flood peak levels. MACE will not be liable for damage caused by
flooding. (The unit is weatherproof, but NOT waterproof and should NOT be
submerged).
2.3 Sunlight
MACE recommends that the FloPro Series 3 electronics module be mounted
so that the LCD faces in a direction away from direct sunlight (ie South in the
Southern Hemisphere and North in the Northern Hemisphere).
2.4 Cable damage
MACE recommends that all cables be appropriately routed through electrical
conduit or other similar mechanism. MACE will not be liable for damage to
cables, especially if it is caused by vehicles, digging implements, animals or
debris in the pipe or channel.
2.5 Insects and moisture
After the FloPro Series 3 system has been installed and fully tested, MACE
recommends the use of expanding “space filler” foam down the first 5 to 10cm
(2 to 4 “) of the conduit or mounting pole to prevent insect/moisture ingress.
1. Does the stream flow that I wish to measure contain sufficient
acoustically reflective particles such as sand, silt, dirt, leaves or air
bubbles? (The stream that you wish to measure must contain at least 100
parts per million of acoustically reflective particles that are greater than
75 microns in size).
Yes – The stream flow is suitable for Doppler ultrasonic flow measurement.
No – The stream flow is unsuitable for Doppler ultrasonic flow measurement.
2. Does the pipe in which I am measuring, run full or partially full?
Full – A velocity only sensor can be used.
Partial – A combined depth/velocity sensor will be required.
3. If the pipe flows full, is the internal pressure of the pipe within the range
0 - 25 m (0 - 253kPa, 0 – 37 psi)?
Yes – The stream flow is suitable for Doppler ultrasonic flow measurement.
No – The stream flow is suitable for Doppler ultrasonic flow measurement.
only if it contains at least 100 parts per million of suspended solids that are
greater than 75 microns in size.
4. Can I get access to the outside wall of the pipe for mounting the sensor?
Yes – Consider using an insert velocity sensor if the pipe runs full.
No – Must use a strap mount sensor internally.
2.6 Battery life
Care must be taken when a mains power supply is used to charge the internal
battery instead of a solar panel. If the mains power remains disconnected
for an extended period of time, the internal battery may be permanently
damaged.
2.7 Electromagnetic compatibility (EMC)
This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.

3.0 Site selection - Continued
5. Does the proposed site have obstructions in the pipe which might cause
irregularities in the flow (eg. elbows, constrictions, valves, gates etc)?
Yes – You will need to install the sensor at a point where there is at least eight
pipe diameters of straight pipe with no obstructions. MACE recommends
that the sensor is mounted so that there is a distance of at least six pipe
diameters of straight pipe in front of it and at least two pipe diameters of
straight pipe behind it.
No – Even when there are no obvious obstructions, MACE recommends
observing the instructions described above.

6. Where is the best place to mount the sensor in a Full pipe?
The sensor should be mounted on the side wall of the pipe, between the
2 and 5 o’ clock positions. A ball valve should be used when mounting
“Insert” type sensor to allow for easy maintenance.
SENSOR MOUNTING POSITION - FULL PIPE
Users are advised to ascertain the suitability of solar panels for
their application by checking relevant solar radiation maps for
their region (for example those found at
http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/atlas/ ).
As a guideline, for an FloPro with 3 Doppler sensors and
measuring every 5 minutes, at least 3 hours sunlight per day

WARNING - Don’t mount the sensor at the top of the pipe as air pockets
could give unreliable readings. Don’t mount the sensor at the bottom
of the pipe as silt build-up can cover the sensor. Only mount the sensor
between 2 and 5 o’clock as shown above.

7. Where is the best place to mount the sensor in a partially full pipe
or channel?
The sensor must be mounted such that the depth sensor is always covered
by water to a depth of at least 50mm (2 inches). Refer diagram over page.
8. Is there likely to be silt build-up over the sensor?
If this is the case, MACE recommends mounting the sensor on the side wall of
the pipe instead of near the bottom of the pipe. Refer diagram over page.
9. Is there enough sunlight for the solar panel to work efficiently?
Yes – Mount solar panel as per instructions
(see 8.1 Solar panel installation on a 2” pole)
No – A mains powered trickle charger should be used to charge the internal
battery.

Return to TOC
NOTE: Sensor should be mounted on the side of the channel when sediment
or weed is present
NOTE: Straight run requirements for open channels are the same as for closed
pipes. The “diameter” to use when calculating your straight run should be the
maximum depth.
10. How far can the sensor be mounted from the electronics module?
A maximum of 50 metres (150ft) of cable is available on any MACE sensor.
11. How do I customise the FloPro Series 3 for my application?
Use the application software, FloCom+ to:
• Configure the unit for your site. For example, this includes setting the pipe
diameter and logging interval.
• View the velocity profile measured by the sensors. This is useful if you think
there may be irregularities in the flow at the site or you want to check the
operation of the unit.
• Download data from the FloPro Series 3.
FloCom+ is available for download at www.macemeters.com

4.0 Sensor types
5.0 Installing an insertion sensor
The FloPro Series 3 sensors measure the amount of water flowing in the pipe
using one of two methods. When the pipe is full, only the velocity of the flow
is measured as the cross sectional area of the flow is constant. In partially full
pipes or open channels, the velocity and depth of the flow are measured in
order to calculate flow rate.
1. Attach a male 2” BSP or NPT nipple to the pipe in a manner suitable for the
pipe material. This fitting must:
• Be at right angles to the flow
• Provide for a clean join inside the pipe (no burring etc)
• Be watertight
4.1 Insertion sensors
1
This type of sensor is used in full pipes where access into the pipe is
impractical or when it may be necessary to remove the sensor in the future
without stopping the flow or emptying the pipe.
Insertion sensors require access to the outside wall of the pipe in which the
sensor is to be mounted. The 2” insertion sensor should be used in pipes that
have a diameter of greater than 100 mm (4”).
MACE recommends that a ball or gate valve is always used when installing
insertion sensors so that sensor maintenance can occur without requiring
the pipe to be emptied of liquid.
WARNING - DO NOT mount this fitting:
• In the centre, at the top of the pipe (may contain trapped air)
• In the centre, on the bottom of the pipe
(may contain a sediment load)
4.2 Strap mount sensors
“Strap mount” type. This type of configuration is used in full pipes when
access to the pipe is available and the pipe can be emptied when installation
or maintenance is required.
“Strap mount velocity/depth” type. This type of sensor must be used in
pipes that run partially full or in open channels.
There are several different types of straps used to hold the “strap mount”
sensors in pipes:
• Plastic expandable mounting straps (polypropylene)
• Mounting plate (polypropylene)
A plastic expandable mounting “strap” can be used to secure the sensor in
place. These straps are made from polypropylene and come in five lengths to
suit different pipe diameters.
• 225-300mm (12” max) • 300-450mm (18” max)
• 450-625mm (25” max) • 600-725mm (29” max)
• 700-810mm (32” max)
Single mounting plates are normally used in large pipes where a costeffective solution is required. The sensor is attached to the plate, which
is then bolted to the inside surface of the pipe. This plate is supplied in
polypropylene.

2. Fit a full bore 2” gate or ball valve to the male nipple, using thread sealant
to ensure that it makes a water tight seal.

3. You are now ready to insert the sensor but first you must determine how
far into the pipe the sensor face needs to be inserted. The sensor face must
be the only thing that intrudes into the flow. Accurate measurements must
be taken to get the values x, y and z as shown in the diagram over the page.
4. Measure value z. Measure from the top of the sensor head to the top of the
sensor shaft. Write the number as your z value.

10. Now that the insertion depth is correct, rotate the sensor so that the grub
screw at the top of the sensor shaft is accurately pointing in the direction of
the longest straight section of pipe. Remember you must have a distance of
at least six pipe diameters of straight pipe in front of the sensor and two pipe
diameters of distance behind the sensor.
NOTE: The grub screw indicates the velocity sensing face.
11. Tighten the 3/4” gland nut to lock the sensor in place.

5. Measure value x. Take a
measurement from the top of
the ball valve to the inside of
the pipe wall. NOTE: You need
the end of the tape measure
to be level with the inside
diameter of the pipe wall.
6. Calculate value y. Value y is
the difference between value x
and value z.
Section A Hardware Manual

5
7. Apply thread sealant onto the thread of the sensor to ensure that it makes
a water tight joint with the valve. Screw the sensor assembly into the valve.
8. Make sure that the 3/4” gland nut is only finger tight. This will allow the
sensor head to be moved freely while the head is aligned into the flow.
9. Open the valve fully and push the sensor head into the flow so it fully
enters the stream without exposing any shaft. To get the sensor in exactly
the right position you need to make the distance between the top of the ball
valve to the top of the sensor shaft the same as value y. Refer to the photos
over page.

Return to TOC
12. When the installation is complete, the sensor shaft should be pointing
directly towards the centre of the pipe in all planes.
13. Carefully route the cable from the sensor back to where the electronics
box will be mounted.
Particular care should be taken when routing cables to ensure
that moisture CANNOT enter the connector of the sensor cable as
permanent damage may occur
MACE recommends that all cables be appropriately routed
through electrical conduit or other similar mechanism.
MACE will not be liable for damage to cables, especially that
caused by vehicles, digging implements, animals or debris in the
pipe or channel

6.0 Installing a sensor on a plastic strap
These plastic (polypropylene) straps are typically used to mount the sensor
in locations where temporary monitoring will take place. They allow for both
very quick installation and removal of a strap mount sensor.
1. Hold the sensor so that you can see the ‘eyes’ of the sensor in front of you,
the sensor cable running to your left
2. Place the mounting strap on the ground or a bench so that you can see the
chamfered edge of the strap in front of you. Place the ‘toe’ of the sensor into
the front of the hole in the strap. Press the body of the sensor down onto
the strap.
3. Turn the whole assembly over. Make sure the cut out in the strap sits
down around the ‘foot’ on the sensor.
4. You should see six countersunk holes in the strap. Fit the six screws
supplied (M3 x 8 mm Phillips head countersunk 304 s/s).
Use only a hand screwdriver. Do not over tighten these screws as
permanent damage to the thread may result
2

7
7. A stainless steel buckle is provided. Slide the buckle onto the mounting
strap as shown.
8. The left side of the strap will simply run through the buckle. The position
of the buckle on the left side of the strap determines the diameter of the
hoop. Therefore, the largest diameter occurs when you first place the buckle
on the strap. The right side of the strap curves around inside the left and
tucks into the buckle. Pick up the left side of the mounting strap and curve it
over to form a semi circle.
9. Bring the right side of the strap up, inside the left and tuck into the
mounting strap. The strap should now form a complete hoop.
10. Position the buckle so that the whole assembly is slightly too large to
comfortably fit in the pipe
11. Now, form a ‘Z’ at the creases in the strap as shown below.
9
11
5. Tie the cable to the plastic strap using the holes and cable ties provided.
Make sure that the knob of the cable tie sits to the back of the assembly, out
of the flow.
6. Place the strap so you are behind the sensor looking upstream.
Upstream is preferred, but not critical as this can be reversed in FloCom+
software. Ensure that minimum straight pipe requirements are still met

6.0 Installing a sensor on a plastic strap - Continued
12. Hold the ‘Z’ with one hand, the sensor with the other and place the
assembly into the pipe reaching as far as is comfortable. Ensure that the
sensor is parallel to the flow and in the bottom part of the pipe, off set to
either side (if there is a build up of debris the sensor will not get covered)
13. Press out the ‘Z’ in the hoop with the palm of your hand. The strap will
‘snap’ into place. You won’t be able to move the mounting strap up or down
the pipe by hand if done properly.
13
13
14. Carefully route the cable from the sensor back to where the electronics
box will be mounted as described in installation of insertion sensors.
Particular care should be taken when routing cables to ensure that
moisture CANNOT enter the connector or the air reference line of the
sensor cable as permanent damage may occur
15. To remove, open the strap by wedging a screwdriver into the flattened ‘Z’
and bearing down on the strap.
14
15
7.0 Installing a sensor using the
mounting plate
The mounting plate consists of a plastic plate with four 6mm clearance holes.
1. Attach the sensor head securely to the mounting plate by the six 3mm
screws supplied (M3 x 8 mm Phillips head countersunk 304 s/s).
Use only a hand screwdriver. Do not over tighten these screws as
permanent damage to the thread may result
1
4
2. Tie the cable to the mounting plate using the holes and cable ties
provided. Make sure that the knob of the cable tie sits to the back of the
assembly, out of the flow.
3. The cable from the sensor to the instrument should then be run inside
the pipe and secured to the pipe in such a manner as to prevent damage by
debris in the pipe. For example, in most cases the cable should be routed
through electrical conduit.
4. Using a fixing method that is suitable for the pipe material, the sensor
plate should be attached to the pipe or channel in a position such that the
sensor is always facing parallel with the pipe.
5. Carefully route the cable from the sensor back to where the electronics
box will be mounted as described in installation of insertion sensors.
Particular care should be taken when routing cables to ensure
moisture CANNOT enter the connector or the air reference line of
the sensor cable as permanent damage may occur

8.0 Installing FloPro power options
8.1 Solar panel installation on a 2” pole
The solar panel is used to charge the internal battery of the FloPro Series 3
where mains power is unavailable.
Users are advised to ascertain the suitability of solar panels for their
application by checking relevant solar radiation maps for their region
(for example those found at http://rredc.nrel.gov/solar/old_data/nsrdb/
redbook/atlas/ ). As a guideline, for a FloPro with three Doppler sensors
and measuring every five minutes, at least three hours sunlight is
required per day
1. Place an M8 bolt with M8 flat washer through the hole in left arm of the
mounting bracket. Ensure that the head of the bolt is on the INSIDE and the
thread faces outward.
2. On the OUTSIDE of the bracket, place an M8 spring washer then an M8 nut.
DO NOT TIGHTEN THE NUT.
3. Repeat these two steps on the right hand side of the bracket.
4. Holding the solar panel carefully, hold it above the two arms of the
mounting bracket.
5. Slide the solar panel down so that the head of each of the M8 bolts fits in
the channel on either side of the solar panel.
5
8. Place the solar panel mounting bracket onto the u-bolt. Ensure that the
arms of the bracket face out from the pole and that the mounting hole on
each arm is towards the top of each arm.
9. Slide the bracket to the desired position on the pole, taking care to place it
at the desired height and so that the open face of the bracket faces towards
the sun.
10. Place the 3/8” flat and spring washers on to the U-bolt and tighten the two
nuts so that the bracket is secured on the pole.
11. Tilt the solar panel so that the active side faces towards the sun (North in
Southern hemisphere, South in Northern hemisphere) at an angle specified
in the data sheet provided. (your latitude + 15°).
11
12
12. Now tighten the M8 nuts on each side of the mounting bracket to secure.
13. The cables from the solar panel/charger to the electronics unit must be
enclosed to minimise exposure to the elements. The cable should be either
routed through conduit or through the solar panel mounting pole. You will
need a hole drilled in the mounting pole at the top near the solar panel as
well as a cut away where the electronics unit is to be mounted. Refer to the
pictures below.
5
13
13
Ensure that the gutter of the solar panel is positioned between the flat
washer and the head of the M8 Bolt
7. Place the u-bolt provided in the solar panel mounting kit around the pole.

8.2 Installing a MACE mains powered trickle charger
In certain applications or where the use of a solar panel is impractical or
undesirable, the FloPro can be powered from any DC source of 16-30 Volts
(2Amps).
When the ambient temperature is less than -10°C (14F), the battery
should be removed to avoid permanent damage to the battery. The
FloPro should be powered by an external power source
1. The charger available from MACE (Part No. 850-323) comes complete with
a circular barrel connector that plugs directly into the electronics module.
See photos over page.
2. If a solar panel is connected to the FloPro as in Chapter 8.1, the internal
charging circuit of the FloPro will also charge the external battery. The
charging circuitry of the FloPro has a 20 Watt capacity.
If the external battery is charged via its own solar panel and NOT
through the FloPro charging circuit, the internal FloPro battery
will discharge completely
The barrel connector for the 16-30VDC charger input is centre positive

10.0 Installing the FloPro on a 2” pole
The sensor and power cables can be routed either directly through the inside
of the 2” mounting pole or through electrical conduit. Installation directions
for both are provided below.
MACE recommends that the FloPro Series 3 electronics module be
mounted so that the LCD faces in a direction away from direct sunlight.
4. Use the two “U” bolts, 3/8” nuts and 3/8” washers provided to secure the
electronics module to the pole.
Do not overtighten the pole mounting bolts as permanent
damage may occur to the electronics enclosure
5. Plug in both the sensor cable and solar panel cable into the sockets as
shown in the picture below.
The Doppler sensor cable should be looped prior to connecting
to act as a form of strain relief. Ensure that the sensor cable is
securely attached by squeezing the slidelock and latching it
in place
10.1 Sensor and power cables routed inside the pole
1. Place the electronics module on a work bench and using a hammer and
screwdriver carefully knock out the plastic cable entry point from the rear
of the enclosure. It is only thin plastic and is designed to break away at the

IMPORTANT: Apply NON-ACIDIC cure silicon sealant to the back of the
electronics module in the channel around the cable entry point. This will
stop water flowing down the pole and into the electronics module.
2. File away any rough edges from the plastic cable entry point
3. Hold the electronics module up against the pole so that the oval cut-away
on the pole matches the cable entry point. Route the sensor and power
cables through the cable entry point as shown.
Ensure that the cable from the solar panel/charger is terminated
using the three-pin connector provided in the electronics box and
that the polarity is correct. The polarity is labelled on the circuit
board near the connector
6. If using a 16-30VDC mains charger then plug this into the socket shown
in the picture below. Alternatively, the charger may be wired into the solar
panel screw terminal block (to the left of the socket).
7. Once all the cables are connected the system should be fully tested.
Assuming everything is connected and fully functional the cable entry point
should be filled with expanding “space filler” foam. This is to prevent insects

19.3 Sensor maintenance
To ensure trouble free data collection, sensors mounted in the flow should
be kept free of built up debris, silt or grease. This is done by using a stiff
bristle brush and carefully cleaning the sensor head and surrounding area.
This process should be repeated as often as necessary in order to keep the
sensors clean. Also check the sensor cable for physical damage.
WARNING: Do not use steel bristle brushes that may cause damage to
either the MACE velocity or depth sensors.
WARNING: For third party sensor maintenance refer to the
documentation supplied with your sensor/s.
19.4 Depth sensor reference filter maintenance
The ceramic depth sensor used by the FloPro Series 3 measures the
hydrostatic pressure of the stream depth. This sensor is vented to
atmospheric pressure via a vent tube inside the sensor cable, which passes
through a filter before entering the silica gel canister that is attached to the
sensor connector and housed within the FloPro Series 3.
In order to keep the depth sensor working properly, this vent tube must
always remain free from moisture.
The silica gel crystals contained within the reference filter effectively entrap
atmospheric moisture. However, these crystals require changing regularly to
ensure that they are still effective.
The silica gel crystals used in the FloPro Series 3 are an indicator type. When
fresh they are a deep blue in colour and when exhausted they are light pink.
The crystals should be replaced when they first appear to be light pink. The
following procedure should be followed to change the crystals:
1. Remove the large rubber stopper on the bottom of the filter housing. (This
is the stopper without the tube attached).
2. Empty the filter chamber of exhausted crystals.
3. Add new crystals (MACE Part No. 590-009) to the filter chamber so that
there is enough room for the rubber stopper to be replaced.
4. Replace the rubber stopper.
This page left intentionally blank
Ensure that the reference filter tube is not crimped as a blockage will
result in incorrect depth readings from the sensor
The longevity of the silica gel crystals is dependent on the amount of
moisture in the atmosphere in which the instrument is mounted. It is
recommended that the crystals be checked at least on a monthly basis
Do not eat the crystals. Wash hands after use

When enabled (via the check box), this function instructs the FloPro to switch
the 12VDC (switched) power line ON for sensors wired to I/O card/s (refer to
chapters 12-14 for wiring details).
A warmup time must be set by the user, suitable for the sensor/s application.
For example, a 4-20mA output downward looking ultrasonic depth sensor
may require a 20 second warm up prior to recording a stable depth reading.

A module is defined in FloCom+ as either a
MACE Doppler velocity card or a MACE I/O card.
1. From the “FloPro Settings” dialogue box click
“Configure modules” and a dialogue box will
appear as shown.
WARNING: The maximum system current available for powering sensors
attached to ALL I/O cards is 1.25 Amps at 12VDC
24.3 View configuration
By clicking “View configuration” the user
is able to see a tree view of all configured
modules and their respective measured
channels.
For example, in the “Module details”
dialogue box opposite, the I/O module in
card slot 2 has four measured channels. The
first is named Depth #2 and the sensor is
wired into the 4-20mA input number 1.
2. Click “Add” and the available modules will be
listed in the “Select module” dialogue box.
3. Each MACE card available is referenced in the

The FloPro Series 3 contains in-built equations for allowing users to measure flow
rate through rated structures such as flumes and weirs. The table below lists the
structures supported and the equations used to calculate flow rate.
All of the weir equations assume that the flow is fully contracted, meaning that
the approach channel is wide enough and deep enough that the proximity of
the floor and sidewalls to the weir opening does not affect the flow (Tony L. Wahl,
Bureau of Reclamation Hydraulics Laboratory in Denver, Colorado, USA).
The equations used by the FloPro Series 3 and reproduced here are used with
permission of U.S. Dept. of the Interior, Bureau of Reclamation - Hydraulic
Investigations and Laboratory Services Group. For further information users are

Monitor status
If this check box is ticked the FloPro will monitor whether or not the sensor is
correctly connected to the Doppler module.
Sensor orientation
Under usual field conditions the velocity sensor should be positioned so that
the transmitted beam is faced upstream. For example, MACE recommends
that the velocity sensor is positioned so that there are 6 pipe diameters of
straight flow before the sensor and 2 pipe diameters of straight flow behind
the sensor. In practice this may not always be possible. However, these
conditions may also be met by positioning the sensor to face downstream for
6 pipe diameters. At poor signal sites, turning the sensor around may help to
increase signal strengths.
The “Orientation” feature allows the user to tell the processing electronics
that although the velocities received are negative (when the sensor is facing
downstream), you wish to totalise this flow as positive flow.
NOTE: When receiving data from a sensor facing downstream, the realtime velocity graph will show a spectrum that appears upside down
Velocity range
This parameter sets the range of expected velocities that are to be analysed.
MACE Flo-series instruments “pigeon-hole” velocity readings into 128
positions over the velocity range set by the user. For example, each “hole” in
a range of 0 - 4 m/s is .03125 m/s wide, whereas in a 0 - 1 m/s range each hole
is .0078 m/s wide. For example, in a stream in which the user knows that the
peak velocity will never exceed say, 0.6 m/s a velocity range of 1 m/s may be
set. In this way, the resolution of the final average velocity is increased.
Furthermore, in slow moving streams or ones that contain few acoustically
reflective particles, a smaller velocity range will often result in far more
repeatable data because the instrument does not waste processing power
gathering data outside of expected ranges. To be safe, the velocity range
should be set larger than expected and the site monitored for several weeks
under different flow conditions to determine the peak expected velocity.
After this period, the user may find it prudent to increase the resolution by
changing the velocity range.
Integration period
The integration time is the period in which samples of the velocity spectrum
are taken before an average velocity reading is calculated. The minimum
integration time is 4 sec and the maximum integration time is 180 seconds
and may be reduced automatically by the measurement interval and
the maximum measurement count depending upon the instrument
configuration.
The integration time may be varied for several reasons:
• Under field conditions where the flow is fluctuating dramatically,
increasing the integration time will help to get a more accurate average
velocity reading, because more samples are available to calculate the
average .
• Under field conditions where the flow has a low number of acoustically
reflective particles, increasing the integration time will help to get a more
accurate average velocity reading, because more reflective targets will be
sampled to calculate the average.
The power consumption of the system is affected by the
integration time. The longer the unit is on and physically
sampling, the shorter the battery life without charging.
The Flo Series3 internal battery has a 7.2 Ah capacity.
During an integration period each Doppler sensor will draw
approximately 120 mA.
Continued over page
The velocity range must be set so that ALL components of the stream
velocity are captured when viewed on the “real-time” graph. Failure
to do so will compromise the validity of the velocity calculation. See
Chapter 29 About real time data for further details

26.3.1 Edit “Velocity” channel type - Doppler card - continued
Maximum measurement count
Under certain flow or no flow conditions signal noise may disrupt the
calculation of a true average velocity reading. As described the peak
threshold feature is designed to overcome this problem. However, unwanted
velocity readings may be derived from other sources such as aquatic life,
which may give strong signal strengths.
Within all Flo-series instruments one of two flow states can occur. The
stream can either be moving or stationary. For example, a Flo-series sensor
submerged in a river diversion pipe that is used to pump irrigation water may
be full at times when no water is being pumped. Under these conditions,
it is common for fish and aquatic invertebrates to inhabit the pipeline.
Unfortunately, to a Doppler ultrasonic velocity sensor, a fish swimming at 500
mm/s is computed as a full pipe of water moving at
500 mm/s. This type of erroneous flow reading will result in an increase in the
totalised flow. Conversely, in a slow moving stream or one that contains few
acoustically reflective particles, a velocity reading may be missed if there is
insufficient data to analyse. Under this circumstance, the totaliser will not be
incremented.
To overcome this problem, MACE Flo-series instruments include the
maximum measurement count feature whereby if the instrument detects a
state change (i.e flow has started or flow has stopped) it stays on and takes
X number of readings to confirm this situation. If all X number of readings
meet the criteria for a valid reading as set by, peak threshold, flow threshold,
minimum stream activity and stream activity percentage, then the reading is
accepted and the change of state confirmed. If the readings do not all agree
that there has been a change of state, then the reading is “discarded” and the
current flow state remains. That is, the unit continues to calculate zero flow or
accepts the flow rate as calculated.
Furthermore, the Flo-series instrument also checks that the direction of flow
has not changed within the X readings. For example, if there is zero flow and
the unit detects a reading of positive flow and another of negative flow then
the overall reading is discarded and the unit continues to register a zero flow.
The number of readings used for the maximum measurement count is
configurable by the user.
70 Section b SOFTware Manual

Calculation method
“Pump method”
Under normal conditions,
water flow that is provided
by a pump is turbulent and
contains a vast number of
acoustically reflective particles, particularly miniature air bubbles that are a
result of cavitation events. In monitoring sites that are pumped, or where
low signal strengths are uncommon, the pump method should be used.
“Surface wave rejection”
In severely turbulent, open
conduit flows such as
encountered in a sewerage
system, it is common for
standing waves to develop in the flow stream. If situated closely, these
standing waves (surface waves) may confound a Doppler ultrasonic sensor
because they typically result in reflections of a significantly slower velocity.
In the diagram, a surface wave can be seen as a sharp peak on the real-time
graph at about the 0.2 m/s mark.
In this case, if the user selects the surface wave rejection calculation
method a menu item called “low-end cutoff” will be displayed. This feature
enables the user to force the Flo-series instrument to ignore Doppler
shifts that lie between zero and the low-end cutoff. The low-end cutoff is
a percentage of the range (x-axis) of the real-time graph. In the diagram
the low-end cutoff would be configured to about 10% of the graph. That
is, any data that are received between 0 and 0.4m/s will be ignored when
computing an average stream velocity (greyed area, not represented in
actual real-time graph).

26.3.1 Edit “Velocity” channel type - Doppler card - continued
“Gravity method”
This method should be used
wherever a stream is slow
moving and/or contains
few acoustically reflective
particles. Because this
calculation method is designed to enhance the velocity processing of slow
moving/clean streams, it may also result in erroneous velocity readings
unless enabled correctly. When enabled, this method will display two new
menu items.
“Minimum stream activity” - Under conditions of zero flow within a
conduit (see maximum measurement count) a single aquatic life form can
produce large Doppler shifts. The minimum stream activity parameter
must be set to negate the effects of these aquatic life forms. This
parameter should be set to low values (2-10) in sites where extremely
slow average velocities are expected (< 0.2 m/s). Values greater than 10
can be set where average velocities of >0.2 m/s are expected.
“Stream activity percentage” - To be used in conjunction with the
minimum stream activity parameter, this parameter forces the Flo-series
instrument to utilise only those velocity spectrums that have a minimum
stream activity value greater than set by the user. Under good acoustic
conditions typically 90 –100% of the data received by the velocity sensor
will be used to calculate an average velocity. Under conditions where
the data received by the velocity sensor has been caused by aquatic
life, typically <10% of the data will be used. Therefore, this parameter
should be set to low values (2-10) in sites where extremely slow average
velocities are expected (< 0.2 m/s). Values greater than 10 can be set
where average velocities of >0.2 m/s are expected.
WARNING: The user MUST check that the value entered for both
“minimum stream activity” and “Stream activity percentage” do not
cause real velocity data to be ignored
72 Section b SOFTware Manual
Return to TOC
“Direction filter” - Under certain field conditions, a stream may move in a
positive direction but the prevailing winds may come from the opposite
(negative) direction. The effect of this on Doppler ultrasonic processing is
that a strong negative Doppler shift may be “seen” as well as the actual
positive shift of the stream itself. In some cases the shift caused by the
winds may overwhelm the shift from the slower moving water flow and
cause erroneous flow rate readings. The “Direction filter” is built in to
allow the user to overcome such sources of error.
“All values” - When checked, all filtering is off.
“Positive only” - When checked, all negative velocity components are
filtered out.
“Negative only” - When checked, all positive velocity components are
filtered out.

WARNING: The user MUST check that the “Direction filter”

Velocity peak threshold
Doppler shifts that are unrelated to the measurement of velocities in a
stream are often called “signal noise”. This “noise” can be a result of several
different factors including:
• Electromagnetic interference;
• Reflections of signals from other echoes.
In some situations background noise may interfere with the calculation of
correct average velocity readings. Flo-series instruments feature a “noise
filter” called a “peak threshold”.
Return to TOC
Mace floPro Series3 Product Manual
73
26.3.1 Edit “Velocity” channel type - Doppler card - continued
In the figure above signal noise can be seen on the velocity spectrum graph
as low signal strength echoes. In the graph above you can see that the signal
noise has an approximate amplitude value of 75. Therefore, by setting a
threshold of say 100, this noise will be ignored in the computation of average
velocity. The user should be careful however, at sites where signal strength
is inherently lower, a peak threshold that is set too high could mean that true
velocity readings are discarded.
This feature is particularly useful at sites where the sensor may be
submerged for periods where no flow is occurring. For example, signal
noise encountered in a submerged 1 m diameter pipeline that gives a false
“average velocity” of 1 m/s will still increase a totalising counter by 785 litres
per second, even though no true flow existed. By watching several realtime graphs of no flow conditions and monitoring the extent of signal noise
apparent, a peak threshold may be set so that signal noise is not computed
as real flow.
Correction Factor
Unfortunately, ideal hydraulic conditions cannot be achieved at every
site that requires monitoring. In locations where hydraulic conditions are
such that velocity calibrations at various flow regimes are required, then
the “Correction factor” may help. Under abnormal hydraulic conditions,
the average velocity of the stream must be calculated using traditional
means that comply with Australian (refer to AS3778 series) or International
Standards.

should be set to 0.95.

If the user has a sensor with known slope and offset characteristics, they
may be entered directly into the unit configuration. For example, the MACE

both metres (m) and inches (in). Be sure to enter the correct values

76 2-point calibration
To correctly calibrate an environmental sensor it is important to calibrate
it over its useful range. For example, if a depth sensor has a range of 0 - 2
metres but you only wish to use it to measure the range 0.1 metres to 1.2
metres, you should re-calibrate it across the reduced range.
Offset adjust
This function is used to “fine tune” the depth reading whenever the sensor
is deployed or reading inaccurately. For example, the depth sensor may
be sitting slightly off the bottom of the stream, or the user has deployed it
above a silt line on the side of a pipe.
1. Click “2-point calibration” from the
“Edit channel” dialogue box and the “2 point
calibration” dialogue box appears.
The “Current value” from the sensor (in this
case a depth sensor with frequency output) is
displayed at the top of the window and is updated
approximately once per second.
2. To carry out a two point calibration, prepare the
measurement set up for the first calibration point
(either the sensors upper or lower range limit).
3. When the “Current value” has stabilised, click on the
“Set” button in the “1st point” box. The “Current value”
is copied to the “Measured value” field of the “1st point”
box and the “Actual value” field is enabled.
4. Enter the sensors actual value (in this case depth) in
the “Actual value” field.
5. Prepare the measurement set up for the second
calibration point (the opposite sensor range limit
from that used in point 2 above). For example, if
you used the upper range limit in point 2, now use
the lower range limit.
6. When the “Current value” has stabilised, click
on the “Set” button in the “2nd point” box. The
“Current value” is copied to the “Measured value”
field of the “2nd point” box and the “Actual value”
field is enabled.
7. Enter the sensors actual value (in this case depth) in
the “Actual value” field.
8. Click on the “Apply” button to calculate the new

Section b SOFTware Manual
WARNING: When calibrating a depth channel, measurements
should ALWAYS be carried out from the bottom of the
channel/pipe to the top of the water level
Manually calculating slope and offset values
Slope = Sensor range ÷ Span
Offset = - (Slope x Sensor output at zero)
Sensor Range: The measuring range of the sensor. For example a depth
sensor may be ranged from 0 to 2m.
Span: Is the difference between the sensor output (Frequency or Voltage) at
the top of the measured range (say 2m) and the sensor output at zero.
For example, you wish to calculate the slope and offset for an ultrasonic
depth sensor that has a range of 0 to 1250mm. At 0mm the sensor outputs a
frequency of 100Hz and at 1250mm the sensor outputs 2500Hz.
The following calculations will provide the sensor’s slope and offset:
Slope = 1250 ÷ (2500-100)
Offset = - (0.5208 x 100)
= 1250 ÷ (2400)
= - 52.08
= 0.5208

Volume increment
Volume increment
The incremental value at which a pulse will be sent. In the example above, a
pulse will be sent whenever an increment of 10 Megalitres is totalised.
RS-232, RS-485 and SDI-12, interfaces are available from the FloPro
Series3 with the use of a FloSI. The FloSI enables users to request the last
measurement from FloPro without the complexity of communicating via the
host communications port.
The FloSI cannot be used to download or configure a FloPro, and only one
serial protocol may be used at one time.
The FloSI requires no routine maintenance and has no user serviceable
components.
Configuration of the FloSI requires MACE Flocom+ (Version 1.1.0.12 or later)
software and successful PC communications with a MACE FloPro Series3
device (Firmware Version 1.00.4 or later). The FloSI configuration settings
are available from the “FloPro settings” dialogue box.
28.1 Configuring a FloSI
1. Establish communications with the device as per Chapter 22 - Connecting
to the device.
2. Ensure at least one module and one channel is configured as per
Chapters 25 - 26. Check the FloSI enabled check box.
3. Click “Configure FloSI“ and the
“FloSI settings” dialogue box will
appear.
NOTE: A maximum of 10 pulses per second may be sent per measurement
interval. For example, during a measurement interval of three minutes
(180 seconds) a maximum of 1,800 pulses can be sent. If the FloPro has
not sent all pulses by the time of the next measurement, pulses WILL
be lost.

The external port is either a standard “RS232” port or a two-wire “RS485”
port, depending on the selected MODBUS mode. The MODBUS parameters
are configurable by entering the appropriate “Address”, selecting the correct
“Baudrate” from the drop down list and checking the required radar buttons.
Select output mode
28.2 Serial Interface Settings
The FloSI can only be configured to use one serial protocol from the three
available. The parameter values are provided in the user configured units.
28.2.1 RS-232, ASCII Mode
The line transmission characteristics are as follows:
Baud rate:
9600
Data bits:
8
Parity:
None
Stop bits:
1
In this mode, the FloSI is dormant while RTS is inactive. On RTS going active,
the FloSI transmits the most current result string from the FloPro Series3. If
RTS is active when a scheduled sample is made, then the string is transmitted
immediately on completion of the measurement.
The transmitted ASCII text string starts with the character ‘ * ‘(asterisk), ends
with a carriage return and contains the configured number of channel
values. The number and order of channel values in the output string can be
configured using Flocom+. Each channel value in the string always begins with
either a ‘+’ (plus sign) or ‘-‘ (minus sign) - there are no spaces between values.

MACE Flo-Series instruments measure average stream velocity using Doppler
ultrasonic technology. Anything moving in the stream, which is acoustically
reflective, may produce an echo and therefore a Doppler shift. Acoustically
reflective particles include:
• Suspended solids;
• Bubbles, eddies and waves;
• Larger particles such as, sand, leaves and pebbles.
When selected in FloCom+, the user can display a real-time graph of the
velocity spectrum received by the velocity sensor. The histogram you see in
real-time data is a composite spectrum of the velocities of the stream flow as
well as various other factors explained below.
• The graph is two dimensional (X-Y).
• The X-axis is the velocity (range set by user).
• The Y-axis (vertical) is the strength of the signal received by the processing
electronics from each velocity sensed in the spectrum.
• Several thousand data points are plotted to give the composite graph. MACE Flo-Series instruments measure several thousand data points and
compute an average velocity. The flow is then calculated using the formula:
Q=V x A
where: Q= Quantity, V= Stream velocity and A= Cross-sectional area.
Users of MACE Flo-Series instruments can use the real time graph to
determine the correct positioning of the velocity sensor by assessing the
shape of the curve and the signal strength. The following graph is an
example of a spectrum that was received from a full pipe irrigation flow.
Under field conditions, several factors can affect the spectrum without
affecting the performance or accuracy of the velocity sensor.
Armed with an understanding of these factors and some field experience,
the operator can vary the position of the sensor and the system settings to
correct site induced errors in the velocity readings.
Return to TOC
Mace floPro Series3 Product Manual
103
29.0 About real time data - continued
If the operator is receiving data such as displayed in the diagram above,
the sensor may be moved slightly to try to overcome the distortion.
Furthermore, the operator should inspect the positioning of the sensor to
ensure that there is not a build-up of debris or other matter, close to the
sensor head. If no obstruction is observed and re-positioning the sensor
does not improve the data, you can be assured that the sensor is operating
effectively and that the displayed data is a site induced phenomenon.
Factors affecting the velocity sensor
This chapter is designed to give the operator a brief understanding of some of
the factors affecting the performance of the MACE Flo-Series velocity sensor.
In flowing streams, there are always a range of different velocities present,
particularly in turbulent water where the effects of eddies and boundary
layers can cause the velocity histogram to appear distorted in the diagram
below. Although distorted, MACE Flo-Series instruments have powerful signal
processing algorithms, which determine the average stream velocity from
these signals.
104 Section b SOFTware Manual
Return to TOC
If data such as that seen above is received, the operator should ensure that
the sensor is positioned correctly and monitor the site for any obstructions
close to the sensor. If no obstructions are located close to the sensor, the
site may be unsuitable to flow measurement with Doppler ultrasonic flow
devices.
The signal strength of received echoes on the real-time histograms, is
a measure of the number of reflective particles moving in the stream.
Therefore, low signal strengths do not necessarily equate to poor velocity
readings. Relatively few particles may provide enough echoes for an
accurate average velocity reading. Furthermore, a histogram with a broad
base will generally tend to have a peak with a lower signal strength. In sites
where it is suspected that there are relatively few reflective particles in the
flow, the period in which the MACE Flo-Series instrument takes readings may
require extending (see, Integration Period on page 69).
Return to TOC
Mace floPro Series3 Product Manual
105
30.0 Real time data
29.0 About real time data - continued
A general rule of thumb, if a spectrum has low signal strength but gives a
consistent velocity reading, then the measurements should be accurate.
However, if the spectrum has low signal strength and gives inconsistent
velocity readings or none at all, the site may be unsuitable for flow
measurement with Doppler ultrasonic flow devices.
Very distorted signals such as that described in the diagram on the previous
page may result from interference to the velocity sensor by the build-up of
debris or siltation.
In sites where there is an expectation of sedimentation, the velocity sensor
should be mounted in a raised position. In a full-pipe application, it is
recommended that the sensor be mounted (or inserted) on the side of the
pipe to avoid sedimentation.
Similarly, in partially full pipes, the sensor may be offset from the invert of the
pipe. In these instances, the depth reading will need to be offset accordingly.
Covering the sensors with algae and other materials that are saturated
generally does not affect the accuracy of velocity readings. This is because
saturated materials exhibit the same speed of sound as water.
MACE Flo-Series instruments include several signal processing features
specifically designed to overcome anomalous data produced by such
phenomena as: aquatic life (fish, weeds, small invertebrates); surface waves
(produced by turbulence and wind); and background noise.
It should always be remembered when examining real-time graphical data,
that settings within the unit itself can have a marked effect on the data
displayed. The configuration of the instrument should always be checked
thoroughly before viewing real-time data.
