Section 2 General Information
2.1 Theory of Operation
The Submerged Area/Velocity Sensor contains a pressure transducer for
level measurement and a pair of ultrasonic transducers for velocity
measurement. These two measurements are used to calculate flow in
open channels.
The flow meter measures the pressure of the water and converts it into a
level reading. The “wetted area” of the flow stream is then calculated using
this level reading and the user-entered channel geometry. The flow meter
then measures the Doppler shift in returned ultrasound and converts it into
a velocity reading. The “wetted area” multiplied by the velocity equals the
flow rate.
2.2 Sensor Overview
The sensor is available in two versions (Figure 1). The Non-oil sensor is used
for reasonably clear sites or in sites where the pipe can become dry.
The Oil-filled sensor is used for sites with high levels of biological growth, grit,
or silt. Do not use the Oil-filled sensor in a pipe that may become dry.

Section 3 Installing the Sensor
3.1 Zeroing the Sensor
The sensor has been factory-calibrated and compensated for temperature.
The sensor needs to be zeroed during each installation, but does not require
calibration. The sensor should be zeroed when moving it from one flow meter
or sample to another.
To zero the sensor:
1.
Install InSight version 5.7 or greater and start the program.
2.
From the InSight software menu, select Remote Programming.
3.
From the Real Time Operations list, select the level sensor to be
calibrated.
4.
Remove the probe from the liquid and place the sensor flat on the
tabletop or floor with the sensor (the plate with the holes) facing down
onto the surface.
5.
Press OK on the dialog box when complete.
3.2 Important Guidelines for Sensor Installation
• Do not install more than one sensor at a time in pipes less than 61 cm
(24 inches). Multiple sensors in smaller pipes can create turbulent or
accelerated flows near the sensors that may cause inaccurate
measurements.
• Mount the sensor as close as possible to the bottom of the pipe invert to
most accurately measure low velocity levels.
• Do not monitor flows in the invert of the manhole itself. The best sensor
location is 3 to 5 times the sewer diameter/height upstream of the invert.
• Locate monitoring sites as far from inflow junctions as possible to avoid
interference caused by combined flows.
• Avoid sites that contain flow obstacles within 2 to 4 pipe diameters in front
of the sensor installation (rocks, stones, pipe joints, valve stems, etc.) as
these will contribute to turbulence and generate high speed flows in the
immediate vicinity of the obstruction.
7726018install.fm
Installing the Sensor
Page 9
Important Guidelines for Sensor Installation
• Avoid any sites with slow moving flows that will encourage the buildup of silt
in the invert or channel. Excessive silting around the sensor may inhibit the
Doppler signal and decrease sensor accuracy, and may affect depth
measurement accuracy.
• Avoid sites with deep, rapid flows that will make it physically difficult or
dangerous to install the sensor.
• Avoid sites with high velocity, low-depth flows. Splash-over and excessive
turbulence will be present around the sensor and data may be inaccurate.
3.2.1
Proper Strain Relief of Sensor Cable
Attach the desiccant hub to the instrument handle to provide a strain relief for
the sensor cable and connector (Figure 2).

Connecting the Sensor to the Mounting Bands
3.3 Connecting the Sensor to the Mounting Bands
Important Note: If using an oil-filled sensor, replenish the oil prior to mounting the
sensor to a mounting band. Refer to section 4.1.2 on page 19 for oil replenishment
instructions, if applicable.
1.
Attach the sensor to the spring ring. Mounting bands come with
pre-drilled holes for direct mounting of the sensor to the band.
2.
To reduce the likelihood of debris collecting on the cable and
mounting band, route the cable along the edge of the band and fasten
the cable to the mounting band with nylon wire ties (Figure 3). The cable
should exit the tied area at, or near, the top of the pipe to keep it out of
the flow stream.
Note: If there is a large amount of silt in the bottom of the pipe, rotate the band until the
sensor is out of the silt (Figure 4), assuring that the sensor remains below the minimum
expected water level at all times. Silt should not be disturbed and must be
measured frequently.

3.4 Placing the Sensor and Mounting Band into the Pipe
Point the angle-face of the sensor into the flow. The manufacturer
recommends placing the sensor with the arrow pointing with the flow
(Figure 5). For other mounting configurations, see the appropriate flow
meter manual.
Slide the mounting band as far into the pipe as possible to eliminate
drawdown effects near the end of the pipe. Locate the sensor at the
bottom-most point in the channel. If excessive silt is present on the bottom
of the pipe, rotate the band in the pipe until the sensor is out of the silt.

Compensating for Velocity Direction
3.5 Compensating for Velocity Direction
When programming the sensor the following may be selected:
Option1
Upstream
(recommended
for most
applications)
Description
Use this option at sites with fairly consistent velocities, and low to medium
turbulence. The flow stream over the sensor should be relatively straight,
with no drops or turns near the measurement point.
Mount the sensor in the pipe, beveled edge facing into the flow, where the
flow stream enters the measurement area (Figure 5).
Use this option when the sensor is installed downstream of the
measurement point (where the flow stream exits the site). This option is
useful when more than one flow stream enters a site and the combined
flow of all streams at a single exit point is measured.
Downstream
Mount the sensor in the downstream direction rather than the typical,
upstream direction. Mounting the sensor 'backwards' in this manner
(Figure 5) causes the velocity direction readings to be the opposite of
actual stream flow. By selecting the Downstream choice when
programming, the logger reverses the measured signal to show actual
flow direction (beveled edge downstream).
The maximum velocity obtained in this type of installation is 5 fps.
1 Additional options may be available depending on the flow meter or sampler used. Refer to
the appropriate flow meter or sampler manual for more information.

Compensating for Velocity Direction
Page 15
Performing a Level Adjustment
3.6 Performing a Level Adjustment
The manufacturer recommends doing a level adjustment whenever a sensor
is first installed into a flow stream. This adjustment accounts for the various
physical tolerance stack-ups in the system (i.e., thickness of the mounting
band, angular placement of the sensor relative to the “6 O’ clock” position in
the pipe, etc.)
1.
With the sensor installed in the flow, use a PC or display (950 and 980
flowmeter) to monitor Current Status.
2.
Take a physical measurement of the water depth by measuring the
distance from the top of the pipe to the surface of the water (item B,
Figure 6), and subtracting this number from the pipe diameter (item A,
Figure 6). The resulting number is the water depth (item C, Figure 6).
3.
Enter the physically-measured water depth into the software using the
Adjust Level function.

Section 4 Sensor Maintenance
4.1 Sensor Maintenance
4.1.1
Cleaning the Sensor (Oil-filled and Standard)
Clean the transducer port when:
• Unexpected increase or decrease in flow or level trend occurs
• Level data are missing or incorrect but velocity data are valid.
• Excessive silt has deposited between the transducer and its
protective cover.
4.1.1.1 Cleaning the Sensor (Oil-filled and Non-oil)
Important Note: Do NOT interchange an oil-filled protective cover plate with a non-oil
cover plate. This will adversely affect level readings. It is possible to convert one type of
sensor to the other using the Oil Probe Conversion Kit (Cat. No. 7730000), refer to the
Oil Probe Conversion Kit Instruction Sheet, Cat. No. 7730089 for more information.
Important Note: When cleaning the transducer, use the most gentle technique
possible. Do not use sharp or pointed objects to remove sediment from the face of the
transducer. If you nick or dent the transducer, it will break!
1.
Soak the sensor in soapy water
Note: Do not soak the sensor in bleach. Bleach will permanently damage the sensor.
Refer to Table 1 for acceptable cleaning solutions.

2.
Remove the screws from the protective cover (Figure 7).
3.
Remove the cover and gasket.
4.
Carefully swirl the sensor in an appropriate cleaning solution to remove
soil. Use a spray or squeeze bottle to wash away heavier deposits.
5.
Clean the gasket and cover. Replace the gasket (Cat. No. 7722000) if it
is torn or damaged. Level readings will be adversely affected if the
gasket is damaged or not installed.
6.
Reattach the gasket and cover (note orientation in Figure 7). Tighten the
screws until the gasket starts to compress.

Oil Replenishment (Oil Kit Cat. No. 7724800)
The manufacturer recommends inspecting the oil in the sensor for large air
bubbles during the customer-scheduled service duty cycle, and prior to every
installation. Small bubbles (less than ¼-in. diameter) of air within the oil do
not affect performance. Larger bubbles may minimize the anti-fouling benefit
of the oil.
To replenish sensor oil:
1.
If the sensor is new, remove the yellow tape on the sensor.
2.
Remove any debris from the sensor.
3.
Load the oil cartridge into the dispensing gun (Figure 9).
4.
Twist the feed tube onto the cartridge and attach the syringe tip to the
feed tube (Figure 10).
5.
Press the dispenser gun handle to purge any air bubbles from the
syringe tip.

6.
Remove the set screw in the transducer cover with the supplied 0.035
hex wrench. Retain the set screw.
7.
Slowly insert the syringe tip into the set screw hole and dispense the oil
(Figure 11). While dispensing the oil, hold the probe at an angle to allow
the air to be pushed out the side port (Figure 11). Continue to dispense
the oil until all the air bubbles are removed.
Note: Slowly insert the syringe tip and do not dispense oil during insertion or damage
to the transducer may occur if too much pressure is applied.
8.
Continue to dispense the oil while removing the syringe from the set
screw hole to prevent air bubbles. Replace the set screw until it is flush
with the transducer cover and remove any excess oil around the screw
hole or on the sensor.
9.
Clean the entire probe and place a piece of electrical tape over the side
port to prevent oil from leaking out. Remove the tape from the sensor
prior to zeroing and installing the sensor.

4.2 Changing the Sensor Desiccant
The desiccant canister contains beads of silica gel which ensure proper
orientation of the pressure transducer. When the beads are blue, they can
remove moisture from the air. When they are pink, they are saturated and
cannot absorb any more moisture from the air, and they must be replaced
immediately.
Important Note: When the beads begin to turn pink, replace or rejuvenate the beads.
Permanent damage to the sensor may occur if the desiccant is not maintained. Never
operate the sensor without the proper desiccant. When rejuvenating beads, remove
them from the canister and heat at 100–180 °C (212–350 °F) until the beads turn blue.
If the beads do not turn blue, replace them with new beads. Do not heat the canister.

4.2.1
Desiccant Replacement Procedure
Note: Replacing the desiccant does not require that the desiccant container be
removed from the desiccant box.
1.
Use a slight twisting motion to twist the bottom end-cap until its slots
align with the retaining clips (Figure 12).
2.
Gently remove the end cap by grasping it and pulling it straight out.
3.
Pour the desiccant beads out of the canister.
4.
Hold the canister up to the light and inspect the hydrophobic filter.
• If you see a small, dim light spot while looking through the hole, the filter
is in good condition. If you see a bright light spot, the filter is probably
torn. Replace the filter.
• If the desiccant beads were completely saturated with water or the filter
has saturated with water or grease, replace the filter.
5.
Refill the canister tube with blue desiccant beads (Cat. No. 3624).
Inspect the O-ring (Cat. No. 5252) on the bottom cap for cracking, pits, or
evidence of leakage. Replace if necessary.
Note: Applying O-ring grease to new or dry O-rings improves the ease of insertion,
sealing, and life span of the O-ring.
6.
Make sure that the O-ring is clean and free of dirt or debris before
replacing the end cap.
7.
Reinstall the end cap.

4.3 Hydrophobic Filter Description
A single Teflon® hydrophobic filter (Cat. No. 3390) is installed in the top of the
canister to prevent liquid from entering the vent tube.
For best performance and to avoid grease buildup on the filter during
submergence or surcharge conditions, hang the canister vertically so that the
end facing the sensor points downward.
Note: The Hydrophobic Filter may need replacement at any time the cartridge is
submerged or exposed to excess moisture. Refer to section 4.4.
4.4 Hydrophobic Filter Replacement Procedure
1.
Disconnect the tubing from the top of the desiccant canister.
2.
Unscrew the hex-head tubing nipple from the top of the canister and
discard the old filter.
3.
Discard any remnants of Teflon tape from the nipple’s threads. Reapply
two turns of Teflon tape (Cat. No. 10851-45) to the threads, pulling the
tape into the threads until it conforms to the shape of the threads.
4.
Place a new filter over the hole. Make sure that the smooth side of the
filter faces the inside of the canister (Figure 13).
5.
Place the threaded nipple on top of the filter.
6.
With a slight pressure, press the filter into the hole with the nipple
threads and begin threading the nipple into the hole. The filter will deflect
upward and feed completely into the thread until it disappears. The filter
must rotate with the nipple as it is threaded into the cap. If it does not, it is
torn. Start over with a new filter.
7.
Inspect the installation. In the upper cap, a small, dim light spot should
be visible when held up to the light. A bright spot indicates a torn filter.
Start over with a new filter.
