Notes for Using FLR-1600A and FLV-4600A Water Flow Devices
►►
►►
►►
►►
►►
►►
USE ONLY PURE, CLEAN DI OR DISTILLED WATER IN THIS DEVICE.
DO NOT use tap water or water with any biological components, minerals
or oils. Any of these substances will affect the viscosity of the water
(creating flow measurement inaccuracies). More importantly, these
impurities will quickly build up in the laminar flow zone, cause corrosion,
and render the measuring capabilities of the device useless. Pure DI
water itself is corrosive to some extent, but it is the contaminants in
your system that will be most detrimental to your FLR-1600A Series
liquid water flow meter.
If you cannot meet the requirement of pure water, then do not use this
water flow device in your application. Damage caused by impurity build
up is not covered by the warranty.
Please read the operating manual that accompanied your device. Keep
the manual for future reference.
When first using the Omega water meter or controller for the day, please
take the following precautions:
1.
Apply your source pressure (approx. 20-30 psig for best results) to
the device with the downstream flow blocked off.
2.
Then slightly open both bleed ports (DO NOT completely remove
the screws) and allow any trapped air to escape. Allow some flow
and let water pass through while bleeding (if the unit is a controller
be sure to give it at least a 50% set-point). See page 10 of the
manual for more information regarding bleed ports and bleeding.
3.
Try not to get any water in-between the black electronics case and
the stainless steel flow body. Wipe up any excess water around
these seams.
4.
Tighten up both bleed screws, and then block the downstream
water flow again. Visually verify zero flow through.
5.
Now you can safely tare (zero) a meter (page 18) using the tare
button on the device, or in the case of a water flow controller,
command the zero set‑point (page 27) which will auto-tare the unit.
Smooth and consistent source pressure is highly preferable, as any pulsing
or fluctuation in water pressure will hydraulically couple to the differential
pressure sensor, and the resultant flow reading will jump analogously.
Please note that, depending on model and flow range, water flow meters
have an inherent internal pressure drop higher than that of standard gas
flow meters of similar flow range. The minimum water device pressure
drop is 2 psig, going all the way to 20 psig drop in certain models. Your
source input pressure must meet or exceed this specification, in addition
to any back pressure you may have on the downstream end of your
process. Please see pages 47 and 49 of the manual.
Please contact Omega if you have any questions. We will be happy to help.

Thank you for purchasing an FLR-1600A Series Water Flow Meter or
FLV‑4600A Water Flow Controller.
Please take the time to find and read the information contained in this
manual. This will help to ensure that you get the best possible service
from your instrument. This manual covers the following instruments:
FLR-1600A Series Water Flow Meters
FLV-4600A Series Water Flow Controllers
FLR-1600A-B Series Portable Water Meters
(Note: All FLR-1600A-B Portable Water Meters operate
in accordance with the instructions found in this manual.
Please see page 46 for information regarding portable meter
operation.)
Please contact Omega if you have any questions regarding the use
or operation of this device.
Many Omega instruments are built for specific applications. Two
instruments with the same flow range and part number may
look and act quite differently depending upon the application the
instrument was built for. Care should be taken when moving an
instrument from one application to another.

MOUNTING
All FLR-1600A Series Meters and FLV-4600A Series Controllers have mounting
holes for convenient mounting to flat panels. The sizes and dimensions for the
mounting holes are shown on pages 50-55.
Meters are position insensitive and can be mounted in any orientation.
Small valve controllers can usually be mounted in any position.
Large valve controllers should be mounted so that the valve cylinder is vertical.
Mounting a large valve controller in another position increases the risk of
leakage when the controller is being held closed by the spring force.
Note: For applications that may continuously introduce occasional air bubbles
to the flow stream upstream of the device, the device may be mounted
upside down to prevent the bubbles from becoming trapped in the differential
pressure sensor ports.
If the device has been installed upside down, avoid using the bleed
screws as water may leak into the electronics housing causing
permanent damage that is not covered under warranty!
PLUMBING
Your controller is shipped with plastic plugs fitted in the port openings.
To lessen the chance of contaminating the flow stream do not remove
these plugs until you are ready to install the device.
Make sure that the water will flow in the direction indicated by the flow arrow.
Standard FLR-1600A Series Meters and FLV-4600A Series Controllers have
female inlet and outlet port connections. Welded VCR and other specialty
fittings may have male ports.
The inlet and outlet port sizes (process connections) for different flow ranges
are shown on pages 50-55.
Instruments with M5 (10-32) ports have O-ring face seals and require no
sealant or tape. Do not use tape with welded or o-ring fittings.
For non-M5 (10-32) ports use thread sealing PTFE tape to prevent leakage
around the port threads.
Do not wrap the first two threads. This will minimize the possibility of getting
tape into the flow stream and flow body.
Do not use pipe dopes or sealants on the process connections as these
compounds can cause permanent damage to the controller should they get
into the flow stream.
When changing fittings, carefully clean any tape or debris from the port threads.
We recommend that a 20 micron filter be installed upstream of meter/
controllers with full scale ranges of 100 ccm or less and a 40 micron filter be
installed upstream of meter/controllers with full scale ranges above 100 ccm.
Avoiding long runs of small diameter tubing upstream or downstream
of the device will reduce water hammer.
8
PRESSURE
Maximum operating line pressure is 100 psig (689 kPa). If the line pressure is
higher than 100 psig (689 kPa), use a pressure regulator upstream from the
flow controller to reduce the pressure to 100 psig (689 kPa)or less.
Although the meter’s operation is uni-directional, reversing the flow direction
will inflict no damage as long as the maximum specified limits are not
exceeded. The differential pressure sensor utilized in this flow meter/controller
is a very sensitive device capable of detecting minute differences in pressure.
Smooth and consistent source pressure is highly preferable, as any pulsing
or fluctuation in water pressure will hydraulically couple to the differential
pressure sensor, and the resultant flow reading will jump analogously.
Please note that, depending on model and flow range, water flow meters have
an inherent internal pressure drop higher than that of standard gas flow meters
of similar flow range. The minimum water device pressure drop is 2 psig, going
all the way to 20 psig drop in certain models. Your source input pressure must
meet or exceed this specification, in addition to any back pressure you may
have on the downstream end of your process.
CAUTION! Exceeding the maximum specified line pressure may
cause permanent damage to the solid-state differential pressure
transducer.
9
BLEED PORTS
FLR-1600A and FLV-4600A-Series flow meters and controllers are equipped
with bleed ports on the front to aid in the removal of air bubbles from the
differential pressure sensor ports. The bleed ports consist of a threaded hole
with an 8-32 nylon tipped screw. After installation or anytime it is suspected
that air may be trapped in the sensor ports, bleed the ports as follows:
A small amount of water will leak from the device during this
procedure. Take necessary precautions to prevent the leaking water
from damaging anything around the unit, taking special care to avoid
any live electrical devices or lines.
1.
With the meter/controller installed and line pressure applied, gently loosen
the upstream bleed port screw 1-2 turns or until water begins to leak from
the threads. DO NOT REMOVE THE SCREW as the port is subject to line
pressures and injury, equipment damage or loss of required parts may result!
2.
Gently tap the flow body (a wooden or plastic screwdriver handle works
well for this) to encourage air bubbles to exit the port.
3.
Any air in the port will generally be removed as the water leaks out even
though you may not see or hear it.
4.
Gently tighten the screw until the leakage stops, taking care not to crush
the nylon tip.
Repeat steps 1-4 with the second bleed port.
8-32 Nylon Tipped Bleed Screw
5/64 Hex Loosen to Bleed
DO NOT REMOVE!
If your device is mounted in an inverted position avoid using the
bleed screws as water may leak into the electronics housing causing
permanent damage that is not covered under warranty!
10
POWER AND SIGNAL CONNECTIONS
Power can be supplied to your meter/controller through either the power jack or
the 8 pin Mini-DIN connector.
An AC to DC adapter which converts line AC power to DC voltage and current as
specified below is required to use the power jack.
A 2.1mm, positive center, 7-30 Vdc AC/DC adapter rated for at least 100 mA is
required to use the adapter jack in a FLR-1600A meter.
A 2.1mm, positive center, 12-30 Vdc AC/DC adapter rated for at least 250 mA is
required to use the adapter jack in a Small Valve controller.
A 2.1mm, positive center, 24-30 Vdc AC/DC adapter rated for at least 500 mA is
required to use the adapter jack in a Large Valve controller.
NOTE: 4-20mA analog output requires at least 15 Vdc.

CAUTION! Do not connect power to pins 1 through 6 as permanent
damage can occur!
It is common to mistake Pin 2 (labeled 5.12 Vdc Output) as the standard 0-5 Vdc
analog output signal. In fact Pin 2 is normally a constant 5.12 Vdc that reflects the
system bus voltage and can be used as a source for the set-point signal.
For DB15 Pin‑outs see pages 57 to 63.

INPUT SIGNALS
Analog Input Signal
Apply analog input to Pin 4 as shown on page 11.
For DB15 Pin‑outs see pages 57 to 63.
Standard 0-5 Vdc is the standard analog input signal. Apply the 0-5 Vdc input
signal to pin 4, with common ground on pin 8.
Optional 0-10 Vdc: If specified at time of order, a 0-10 Vdc input signal can be
applied to pin 4, with common ground on pin 8.
Optional 4-20 mA: If specified at time of order, a 4-20 mA input signal can be
applied to pin 4, with common ground on pin 8.
NOTE: This is a current sinking device. The receiving circuit is essentially a 250
ohm resistor to ground.
NOTE: 4-20mA output requires at least 15 Vdc power input.
CAUTION! Do not connect this device to “loop powered’”
systems, as this will destroy portions of the circuitry and void
the warranty. If you must interface with existing loop powered
systems, always use a signal isolator and a separate power supply.

OUTPUT SIGNALS
RS232 / RS485 Digital Output Signal
To use the RS232 or RS485 output signal, it is necessary to connect the RS232 /
RS485 Output Signal (Pin 5), the RS232 / RS485 Input Signal (Pin 3), and Ground
(Pin 8) to your computer serial port as shown on page 8. (See page 31 for
details on accessing RS232 / RS485 output.)
Standard Voltage (0-5 Vdc) Output Signal
Meters/controllers equipped with a 0-5 Vdc (optional 0-10 Vdc) will have this
output signal available on Pin 6. This output is generally available in addition to
other optionally ordered outputs. This voltage is usually in the range of 0.010
Vdc for zero flow and 5.0 Vdc for full-scale flow. The output voltage is linear
over the entire range. Ground for this signal is common on Pin 8.
Optional 0-10 Vdc Output Signal
If your meter/controller was ordered with a 0-10 Vdc output signal, it will be
available on Pin 6. (See the Calibration Data Sheet that shipped with your meter
to determine which output signals were ordered.) This voltage is usually in the
range of 0.010 Vdc for zero flow and 10.0 Vdc for full-scale flow. The output
voltage is linear over the entire range. Ground for this signal is common on Pin 8.
Optional Current (4-20 mA) Output Signal
If your meter/controller was ordered with a 4-20 mA current output signal, it
will be available on Pin 1. (See the Calibration Data Sheet that shipped with
your meter to determine which output signals were ordered.) The current
signal is 4 mA at 0 flow and 20 mA at the meter’s full scale flow. The output
current is linear over the entire range. Ground for this signal is common on Pin
8. (Current output units require 15-30 Vdc power.)
Optional 2nd Analog Output Signal
You may specify an optional 2nd analog output on Pin 2 at time of order. (See
the Calibration Data Sheet that shipped with your meter to determine which
output signals were ordered.) This output may be a 0-5 Vdc, 0-10 Vdc, or
4-20 mA analog signal that can represent any measured parameter. With this
optional output, a meter could output the volume flow rate (0-5 Vdc on pin 6)
and the line temperature (0-5 Vdc on pin 2).
If your device is equipped with the optional six pin industrial connector,
please contact Omega.
CAUTION! Do not connect this device to “loop powered’”
systems, as this will destroy portions of the circuitry and void
the warranty. If you must interface with existing loop powered
systems, always use a signal isolator and a separate power supply.

The following parameters are displayed in

Line Pressure: Only on units equipped with
the optional pressure sensor, pressing
the PSIG button will move the line gauge
pressure to the primary display.
Line Temperature: Pressing the °C button
will move the process temperature to the
primary display.
Pushing the button again allows you to
select 0C (Celsius), K (Kelvin), 0F (Fahrenheit)
or 0R (Rankine) for the temperature scale.
To select a temperature scale, use the LN‑UP
and LN-DN buttons to position the arrow in
front of the desired scale.
Press SET to record your selection and
return to the MAIN display. The selected
temperature scale will be displayed on
the screen.
Tare: Pushing the TARE V button tares the
flow meter and provides it with a reference
point for zero flow. This is an important
step in obtaining accurate measurements.
It is best to zero the flow meter each time
it is powered up. If the flow reading varies significantly from zero after an initial
tare, give the unit a minute or so to warm up and re-zero it.
CANCEL
SET
If possible, zero the unit near the expected operating pressure by positively blocking
the flow downstream of the flow meter prior to pushing the TARE button.
Zeroing the unit while there is any flow will directly affect the accuracy
by providing a false zero point. If in doubt about whether a zero flow
condition exists, remove the unit from the line and positively block both
ports before pressing the TARE button. If the unit reads a significant negative
value when removed from the line and blocked, it was given a false zero. It
is better to zero the unit at atmospheric pressure and a confirmed no flow
condition than to give it a false zero under line pressure.
It is not uncommon for a meter to read a small value when it is removed from
the process line as water can “hang” in one or both of the differential pressure
sensor ports. If the unit reads a significant negative value when removed from
the line and blocked, it is a good indication that it was given a false zero.

Volume: The volume flow rate is defaulted on the primary display. Press the
unit of measure button (ccm in the example) to return the volume flow rate to

Volume means that the controller is
“closing the loop” on the volume flow

the controller a set-point, the controller
compares that set-point to the measured
volume flow rate and adjusts the valve
to try to make the flow and the set-point
match. For the volume flow rate, the input

PID Values determine the performance
and operation of your proportional
control valve. These terms dictate control
speed, control stability, overshoot and
oscillation. All units leave the factory with
a generic tuning designed to handle most
applications. If you encounter issues with
valve stability, oscillation or speed, fine
tuning these parameters may resolve the
problem.

The PD algorithm is the PID algorithm used on most FLV-4600A controllers.
It is divided into two segments:
The first compares the process value to the set-point to generate a proportional
error. The proportional error is multiplied by the ‘P’ gain, with the result added
to the output drive register.
The second operates on the present process value minus the process value during
the immediately previous evaluation cycle. This ‘velocity’ term in multiplied by
the ‘D’ gain, with the result subtracted from the output drive register.
The above additions to and subtractions from the output drive register
are carried over from process cycle to process cycle, thus performing the
integration function automatically.
Increasing the ‘P’ gain will promote the tendency of the system to overshoot,
ring, or oscillate.
Increasing the ‘D’ gain will reduce the tendency of the system to overshoot.
The PD2I algorithm is a PID algorithm used primarily for high performance
pressure and flow control applications.
It exhibits two basic differences from the PD algorithm that most controllers utilize.
1. Instead of applying a damping function based upon the rate of change of the
process value, it applies a damping function based upon the square of the rate of
change of the process value.
2. The damping function is applied directly to the proportional error term
before that term is used in the proportional and integral functions of the
algorithm. This provides a certain amount of ‘look ahead’ capability in the
control loop.
Because of these differences, you will note the following:
1. Increasing ‘P’ gain can be used to damp out overshoot and slow oscillations
in pressure controllers. You will know that ‘P’ gain is too high, when the
controller breaks into fast oscillations on step changes in set-point. On flow
controllers, too high a ‘P’ gain results in slower response times. Too low a ‘P’
gain results in overshoot and/or slow oscillation. A good starting value for ‘P’
gain is 200.
2. If the unit was originally shipped with the PD2I algorithm selected, the
‘D’ gain value should be left at or near the factory setting because it relates
primarily to the system phase lags. If you are changing from the default
algorithm to the PD2I algorithm, you should start with a ‘D’ gain value of 20.
3. The ‘I’ gain is used to control the rate at which the process converges
to the set-point, after the initial step change. Too low a value for ‘I’ gain
shows up as a process value that jumps to near the set-point and then takes
awhile to converge the rest of the way. Too high a value for ‘I’ gain results in
oscillation. A good starting value for the ‘I’ gain is 200.

Open your HyperTerminal® RS232 / RS485 terminal program (installed under
the “Accessories” menu on all Microsoft Windows® operating systems).
Select “Properties” from the file menu.
Click on the “Configure” button under the “Connect To” tab. Be sure the
program is set for: 19,200 baud (or matches the baud rate selected in the
RS232 / RS485 communications menu on the meter) and an 8-N-1-None (8
Data Bits, No Parity, 1 Stop Bit, and no Flow Control) protocol.
Under the “Settings” tab, make sure the Terminal Emulation is set to ANSI
or Auto Detect.
Click on the “ASCII Setup” button and be sure the “Send Line Ends with Line
Feeds” box is not checked and the “Echo Typed Characters Locally” box
and the “Append Line Feeds to Incoming Lines” boxes are checked. Those
settings not mentioned here are normally okay in the default position.
Save the settings, close HyperTerminal® and reopen it.
Streaming Mode (RS485 units do not have a streaming mode)
In the default Polling Mode, the screen should be blank except the blinking cursor.
In order to get the data streaming to the screen, hit the “Enter” key several times
to clear any extraneous information. Type “*@=@” followed by “Enter” (or using
the RS232 / RS485 communication select menu, select @ as identifier and exit
the screen). If data still does not appear, check all the connections and COM port
assignments.
Streaming Mode – Advanced
The streaming data rate is controlled by register 91. The recommended default rate
of data provision is once every 50 milliseconds and this is suitable for most purposes.
If a slower or faster streaming data rate is desired, register 91 can be changed to a
value from 1 millisecond to 65535 milliseconds, or slightly over once every minute.
Below approximately 40 milliseconds, data provision will be dependent upon
how many parameters are selected. Fewer data parameters can be streamed
more quickly than more. It is left to the user to balance streaming speed with
number of parameters streamed.
To read register 91, type “*r91” followed by “Enter”.
To modify register 91, type “*w91=X”, where X is a positive integer from 1 to
65535, followed by “Enter”.
To return to the recommended factory default streaming speed, type “*w91= 50”.
31
Tareing via RS232 / RS485 (FLR-1600A Series only):
Tareing (or zeroing) the flow meter provides it with a reference point for
zero flow. This is a very simple but important step in obtaining accurate
measurements. It is good practice to “zero” the flow meter each time it is
powered up.
If the flow reading varies significantly from zero after an initial tare, give the
unit a minute or so to warm up and re-zero it. If possible, it is helpful to zero
the unit near the expected operating pressure by positively blocking the flow
downstream of the flow meter prior to entering the Tare command. Zeroing the
unit while there is any flow will directly affect the accuracy by providing a false
zero point.
If in doubt about whether the flow is positively blocked, remove it from the line
and positively block both ports before entering the Tare command. If the unit
reads a significant negative value when removed from the line and blocked, it
is a good indication that it was given a false zero. It is better to zero the unit at
atmospheric pressure and a confirmed no flow conditions than to give it a false
zero under line pressure. To send a Tare command via RS232 / RS485, enter the
following strings:
In Polling Mode:
Address$$V<Enter>
(e.g. B$$V<Enter>)
Sending a Set-point via RS232 / RS485: To send a set-point via RS232 / RS485,
“Serial” must be selected under the “Input” list in the control set up mode.
Method 1: Set-point may be set in floating point in serial communication using
serial command (UnitID)SX.YZ
Example: AS4.54 results in Unit ID A changing set-point to 4.54.
Method 2: Type in a number between 0 and 65535 (2% over range), where 64000
denotes full-scale flow rate, and hit “Enter”.
The set-point column and pressure rates should change accordingly. If they do
not, try hitting “Enter” a couple of times and repeating your command. The
formula for performing a linear interpolation is as follows:
Value = (Desired Set-point X 64000) / Full Scale Flow Range
For example, if your device is a 500 ccm full-scale unit and you wish to apply a
set-point of 125 ccm you would enter the following value:
16000 = (125 ccm X 64000) / Full Scale Flow Range
If the controller is in polling mode as described in Changing from Streaming
Mode to Polling Mode, the set-point must be preceded by the address of the
controller. For example, if your controller has been given an address of D, the
set-point above would be sent by typing:
D16000 followed by “Enter”
32
To adjust the Proportional and Differential (P&D) terms via RS232 / RS485
(FLV-4600A Series only):
Type *@=A followed by “Enter” to stop the streaming mode of information.
To adjust the “P” or proportional term of the PID controller, type *R21
followed by “Enter”.
The computer will respond by reading the current value for register 21 between
0-65535. It is good practice to write this value down so you can return to the
factory settings if necessary. Enter the value you wish to try by writing the new
value to register 21. For example, if you wished to try a “P” term of 220, you
would type *W21=220 followed by “Enter” where the bold number denotes the
new value.
The computer will respond to the new value by confirming that 21=220. To
see the effect of the change you may now poll the unit by typing A followed
by “Enter”. This does an instantaneous poll and returns the values once. You
may type A “Enter” as many times as you like. Alternately, you could resume
streaming mode by typing *@=@ followed by “Enter”. Repeat step 3 to remove
the unit from the streaming mode.
To adjust the “D” or proportional term of the PID controller, type *R22 followed
by “Enter”.
The computer will respond by reading the current value for register 22 between
0-65535. It is good practice to write this value down so you can return to the
factory settings if necessary. Enter the value you wish to try by writing the new
value to register 22. For example, if you wished to try a “D” term of 25, you
would type *W22=25 followed by “Enter” where the bold number denotes the
new value.
The computer will respond to the new value by confirming that 22=25. To
see the effect of the change you may now poll the unit by typing A followed
by “Enter”. This does an instantaneous poll and returns the values once. You
may type A “Enter” as many times as you like. Alternately you could resume
streaming mode by typing *@=@ followed by “Enter”. Repeat.
You may test your settings for a step change by changing the set-point. To do
this type A32000 (A is the default single unit address, if you have multiple
addressed units on your RS232 / RS485 line the letter preceding the value
would change accordingly.) followed by “Enter” to give the unit a ½ full scale
set-point. Monitor the unit’s response to the step change to ensure it is
satisfactory for your needs. Recall that the “P” term controls how quickly the
unit goes from one set-point to the next, and the “D” term controls how quickly
the signal begins to “decelerate” as it approaches the new set-point (controls
the overshoot).
33
Changing From Streaming to Polling Mode:
When the meter is in the Streaming Mode (RS485 units do not have a streaming
mode), the screen is updated approximately 10-60 times per second (depending
on the amount of data on each line) so that the user sees the data essentially in
real time. It is sometimes desirable, and necessary when using more than one
unit on a single RS232 line, to be able to poll the unit.
In Polling Mode the unit measures the flow normally, but only sends a line of
data when it is “polled”. Each unit can be given its own unique identifier or
address. Unless otherwise specified each unit is shipped with a default address
of capital A. Other valid addresses are B thru Z.
Once you have established communication with the unit and have a stream of
information filling your screen:
1.
Type *@=A followed by “Enter” (or using the RS232 / RS485
communication select menu, select A as identifier and exit the screen) to
stop the streaming mode of information. Note that the flow of information
will not stop while you are typing and you will not be able to read what you
have typed. Also, the unit does not accept a backspace or delete in the line
so it must be typed correctly. If in doubt, simply hit enter and start again. If
the unit does not get exactly what it is expecting, it will ignore it. If the line
has been typed correctly, the data will stop.
2.
You may now poll the unit by typing A followed by “Enter”. This does an
instantaneous poll of unit A and returns the values once. You may type A
“Enter” as many times as you like. Alternately you could resume streaming
mode by typing *@=@ followed by “Enter”. Repeat step 1 to remove the
unit from the streaming mode.
3.
To assign the unit a new address, type *@=New Address, e.g. *@=B. Care
should be taken not to assign an address to a unit if more than one unit
is on the RS232 / RS485 line as all of the addresses will be reassigned.
Instead, each should be individually attached to the RS232 / RS485 line,
given an address, and taken off. After each unit has been given a unique
address, they can all be put back on the same line and polled individually.
34
Collecting Data:
The RS232 / RS485 output updates to the screen many times per second.
Very short-term events can be captured simply by disconnecting (there are
two telephone symbol icons at the top of the HyperTerminal® screen for
disconnecting and connecting) immediately after the event in question. The
scroll bar can be driven up to the event and all of the data associated with
the event can be selected, copied, and pasted into Microsoft® Excel® or other
spreadsheet program as described below.
For longer term data, it is useful to capture the data in a text file. With the
desired data streaming to the screen, select “Capture Text” from the Transfer
Menu. Type in the path and file name you wish to use. Push the start button.
When the data collection period is complete, simply select “Capture Text” from
the Transfer Menu and select “Stop” from the sub-menu that appears.
Data that is selected and copied, either directly from HyperTerminal® or from
a text file can be pasted directly into Excel®. When the data is pasted it will all
be in the selected column. Select “Text to Columns...” under the Data menu in
Excel® and a Text to Columns Wizard (dialog box) will appear. Make sure that
“Fixed Width” is selected under Original Data Type in the first dialog box and
click “Next”. In the second dialog box, set the column widths as desired, but
the default is usually acceptable. Click on “Next” again. In the third dialog box,
make sure the column data format is set to “General”, and click “Finish”. This
separates the data into columns for manipulation and removes symbols such
as the plus signs from the numbers. Once the data is in this format, it can be
graphed or manipulated as desired.
For extended term data capture see: “Sending a Simple Script to
HyperTerminal®” on page 37.

Data Format:
The data stream on the screen represents the flow parameters of the main
mode in the units shown on the display. For FLR-1600A Series Flow Meters,
there are three columns of data. The first column is line pressure (normally in
psig and only in units equipped with the optional pressure sensor), the second
column line temperature (normally in °C), and the third column is the volume
flow rate in the units specified at time of order and shown on the display.

FLR-1600A Series Water Flow Meter Data Format
For FLV-4600A Series Flow Controllers, there are four columns of data
representing pressure, temperature, volume flow and set-point. The first
column is line pressure (normally in psig and only in units equipped with the
optional pressure sensor), the second column is temperature (normally in °C),
the third column is volume flow rate (in the units specified at time of order and
shown on the display), and the fourth column is the set-point (also in the units
specified at time of order and shown on the display). For instance, if the meter
was ordered in units of ccm, the display on the meter would read 2.004 ccm
and the last two columns of the output below would represent volume flow
and set-point in ccm respectively.

Sending a Simple Script File to HyperTerminal®
It is sometimes desirable to capture data for an extended period of time.
Standard streaming mode information is useful for short term events, however,
when capturing data for an extended period of time, the amount of data
and thus the file size can become too large very quickly. Without any special
programming skills, you can use HyperTerminal® and a text editing program
such as Microsoft® Word® to capture text at defined intervals.
1. Open your text editing program, MS Word for example.
2. Set the cap lock on so that you are typing in capital letters.
3. Beginning at the top of the page, type A<Enter> repeatedly. If you’re using
MS Word, you can tell how many lines you have by the line count at the bottom
of the screen. The number of lines will correspond to the total number of times
the flow device will be polled, and thus the total number of lines of data it will
produce.
For example:
A
A
A
A
A
A
will get a total of six lines of data from the flow meter, but you can
enter as many as you like.
The time between each line will be set in HyperTerminal.
4. When you have as many lines as you wish, go to the File menu and select
save. In the save dialog box, enter a path and file name as desired and in the
“Save as Type” box, select the plain text (.txt) option. It is important that it be
saved as a generic text file for HyperTerminal to work with it.
5. Click Save.
6. A file conversion box will appear. In the “End Lines With” drop down box,
select CR Only. Everything else can be left as default.
7. Click O.K.
8. You have now created a “script” file to send to HyperTerminal. Close the file
and exit the text editing program.
9. Open HyperTerminal and establish communication with your flow device as
outlined in the manual.
10. Set the flow device to Polling Mode as described in the manual. Each time
you type A<Enter>, the meter should return one line of data to the screen.
11. Go to the File menu in HyperTerminal and select “Properties”.
12. Select the “Settings” tab.
37
13. Click on the “ASCII Setup” button.
14. The “Line Delay” box is defaulted to 0 milliseconds. This is where you will
tell the program how often to read a line from the script file you’ve created.
1000 milliseconds is one second, so if you want a line of data every 30 seconds,
you would enter 30000 into the box. If you want a line every 5 minutes, you
would enter 300000 into the box.
15. When you have entered the value you want, click on OK and OK in the
Properties dialog box.
16. Go the Transfer menu and select “Send Text File…” (NOT Send File…).
17. Browse and select the text “script” file you created.
18. Click Open.
19. The program will begin “executing” your script file, reading one line at
a time with the line delay you specified and the flow device will respond by
sending one line of data for each poll it receives, when it receives it.
You can also capture the data to another file as described in the manual
under “Collecting Data”. You will be simultaneously sending it a script file and
capturing the output to a separate file for analysis.
FLOW MEASUREMENT OPERATING PRINCIPLE
All FLR-1600A or FLV-4600A Series Water Flow Meters/Controllers accurately
determine the flow rate by creating a pressure drop across a unique internal
restriction, known as a Laminar Flow Element (LFE), and measuring differential
pressure across it. The restriction is designed so that the water molecules are
forced to move in parallel paths along the entire length of the passage; hence
laminar (streamline) flow is established for the entire range of operation of
the device. Unlike other flow measuring devices, in laminar flow meters the
relationship between pressure drop and flow is linear.
In order to have an accurate reading of the flow rate, the absolute viscosity of
the fluid must be established. The rate at which liquids change viscosity with
changes in temperature is not linear. The relationship between temperature
and viscosity for water is well established and FLR-1600A and FLV-4600A Series
units utilize a high accuracy temperature sensor and this relationship to provide
an accurate viscosity reference. For this reason, these meters and controllers
are generally recommended only for use with pure water. Any additives to
water (such as antifreeze or disinfectants) that might affect the viscosity should
be avoided.

TROUBLESHOOTING
Display does not come on or is weak.
Check power and ground connections and supply voltage. Please reference
the technical specifications (page 50-55) to assure you have the proper power
for your model.
Flow reading is approximately fixed either near zero or near full scale regardless of
actual line flow.
Differential pressure sensor may be damaged. A common cause of this problem
is instantaneous application of high pressure as from a snap acting solenoid
valve upstream of the meter. If you suspect that your pressure sensor is
damaged please discontinue use of the device and contact Omega.
Displayed volumetric flow, pressure or temperature is flashing and message
VOV, POV or TOV is displayed:
Our flow meters and controllers display an error message (VOV = volumetric
overrange, POV = pressure overrange, TOV = temperature overrange) when
a measured parameter exceeds the range of the sensors in the device. When
any item flashes on the display, neither the flashing parameter nor the flow
measurement is accurate. Reducing the value of the flashing parameter to
within specified limits will return the unit to normal operation and accuracy. If
the unit does not return to normal contact Omega.
Meter reads negative flow when there is a confirmed no flow condition.
This is an indication of an improper tare. If the meter is tared while there is
flow, that flow is accepted as zero flow. When an actual zero flow condition
exists, the meter will read a negative flow. Simply re-tare at the confirmed
zero flow condition. Also note that while the meter is intended for positive
flow, it will read negative flow with reasonable accuracy (it is not calibrated for
bi‑directional flow) and no damage will result. See TARE page 18.
After installation, there is no flow.
FLV-4600A Series controllers incorporate normally closed valves and require a
set-point to operate. Check that your set-point signal is present and supplied to
the correct pin and that the correct set-point source is selected under the SETPT
SOURCE list in the control set up display (page 26). Also check that the unit is
properly grounded.
My controller does not respond to the set-point.
Check that your set-point signal is present and supplied to the correct pin and
that the correct set-point source is selected under the SETPT SOURCE list in the
control set up display (page 27). Also check that the unit is properly grounded.
The flow lags below the set-point.
Be sure there is enough pressure available to make the desired flow rate. If
either the set-point signal line and/or the output signal line is relatively long, it
may be necessary to provide heavier wires (especially ground wiring) to negate
voltage drops due to line wire length. An inappropriate PID tuning can also
cause this symptom if the D term is too large relative to the P term (page 29).
41
Meter does not appear to be accurate when compared against another valid
measurement of the physical flow (such as weight over time).
Water flow meters can normally be compared against one another provided
there are no leaks between the two meters. One common cause of inaccuracy,
inconsistency, or unusual readings is air bubbles trapped in one or both of the
legs of the differential pressure sensor. Bleed the ports as described in this
manual to remove this possibility (See page 10). Another possibility is that the
water has some contaminant or additive, such as antifreeze, that affects the
viscosity of the water. A third possibility is an improper tare error (see page 18).
Controller is slow to react to a set-point change or imparts an oscillation to the flow.
An inappropriate PID tuning can cause these symptoms. Use at conditions
considerably different than those at which the device was originally set up can
necessitate a re-tuning of the PID loop (page 29).
Flow flutters or is jumpy.
The meters are very fast and will pick up any actual flow fluctuations such
as from a diaphragm pump, etc. Also, inspect the inside of the upstream
connection for debris such a PTFE tape shreds. Note: FLR-1600A & FLV-4600A
Series devices feature a programmable geometric running average (GRA) that
can aid in allowing a rapidly fluctuating flow to be read. Please see “Pressure
Averaging” and “Flow Averaging” on page 21.
The output signal is lower than the reading at the display.
This can occur if the output signal is measured some distance from the meter
as voltage drops in the wires increase with distance. Using heavier gauge wires,
especially in the ground wire, can reduce this effect.
My controller oscillates wildly and/or exhibits very different reactions to the setpoint than I expect.
Conditions considerably different than those at which the device was originally
set up can necessitate a re-tuning of the PID loop. Avoid long runs of small
diameter tubing in the system, increase line size.
RS232 / RS485 Serial Communications is not responding.
Check that your meter is powered and connected properly. Be sure that the port
on the computer to which the meter is connected is active. Confirm that the port
settings are correct per the RS232 / RS485 instructions in this manual (Check the
RS232 / RS485 communications select screen for current meter readings). Close
HyperTerminal® and reopen it. Reboot your PC. See pages 12, 13 and 31 for more
information on RS232 / RS485 signals and communications.
Slower response than specified.
FLR-1600A Series Meters and FLV-4600A Series Controllers feature a
programmable Geometric Running Average (GRA). Depending on the full scale
range of the meter, it may have the GRA set to enhance the stability/readability
of the display, which would result in slower perceived response time. Please see
“Pressure Averaging” and “Flow Averaging” on page 21.
42
Jumps to zero at low flow.
FLR-1600A Series Meters and FLV-4600A Series Controllers feature a
programmable zero deadband. The factory setting is usually 0.5% of full scale.
This can be adjusted between NONE and 6.3% of full scale. See page 21.
MAINTENANCE AND RECALIBRATION
General: FLR-1600A and FLV-4600A Series Water Flow Meters and Controllers
require minimal maintenance. The primary cause of damage and/or long-term
inaccuracy in these devices is contamination and/or corrosion damage. Water
should be filtered for particulates or biological materials that may grow in the
device. When removing these units from the line for any extended period of
time, make an effort to remove all of the water from the device, as deposits of
calcium or other soluble minerals can affect the accuracy of the device.
Recalibration: The recommended period for recalibration is once every year. A
label located on the back of the device lists the most recent calibration date.
The device should be returned to the factory for recalibration within one year
from the listed date. Before calling to schedule a recalibration, please note the
serial number on the back of the meter. The Serial Number, Model Number, and
Date of Manufacture are also available on the Model Info screen (page 23).
Cleaning: FLR-1600A and FLV-4600A Series Flow Meters/Controllers require no
periodic cleaning. If necessary, the outside of the meter can be cleaned with a
soft dry cloth. Avoid excess moisture or solvents.
For repair, recalibration or recycling of this product, contact Omega.

Option: Totalizing Mode
Meters and controllers can be purchased with the Totalizing Mode option. For
controllers this option adds an additional mode screen that displays the total
flow (normally in the units of the main flow screen) that has passed through the
device since the last time the totalizer was cleared. The Totalizing Mode screen is
accessed by pushing the TOTAL button on the MAIN display.
TOTAL/TIMER: Pushing the TOTAL/TIMER button will cycle the large numbers on the
display between total mass and time elapsed.

Rollover with Notification – When the counter
reaches the maximum count it automatically
rolls over to zero, displays an overflow error, and continues counting until the
counter is cleared.
TOTAL MASS: The counter can have as many as seven digits. At the time of order,
the customer must specify the range. This directly affects the maximum count. For
instance, if a range of 1/100ths of a liter is specified on a meter which is totalizing in
liters, the maximum count would be 99999.99 liters. If the same unit were specified
with a 1 liter range, the maximum count would be 9999999 liters.
00123.45
ELAPSED TIME: The small numbers below the mass total show the elapsed time
since the last reset in hours, minutes and seconds. The maximum measurable
elapsed time is 9999 hours 59 minutes 59 seconds. The hours count resets when
RESET is pushed, an RS232 or RS485 clear is executed or on loss of power. Press
TOTAL/TIMER to show this as the primary display.
PEAK (Meters Only): PEAK will display the most recent peak flow rate until
totalizer is reset.
SETPT (Controllers Only): Pushing SETPT will allow you to change the controller's
set-point.
RESET – The counter can be reset to zero at any time by pushing the RESET
button. To clear the counter via RS232 or RS485, establish serial communication
with the meter or controller as described in the RS-232 or RS-485 section of the
manual. To reset the counter, enter the following commands:
In Polling (addressable) Mode: Address$$T <Enter> (e.g. B$$T <Enter>)
When using a mass flow controller as an absolute pressure controller,
the mass flow rate may momentarily exceed the flow measurement
capability (full scale + 28%) of the unit. This may occur when the unit is
asked to make an abrupt pressure change.
If the totalizer is in use at that time, the totalized value will necessarily become
incorrect. Please reset the totalizer if such an ‘over-flow’ condition has occurred.

The new batch begins when you press RESET.
- To continue the existing batch to a larger total
volume, increase the Batch value. Flow resumes as
soon as you press OK in the Batch Value screen.
- To start a larger batch from scratch, first clear the
flow Set-Point to zero to prevent unwanted flow.
Then increase the Batch value, and select a flow Set-Point. Flow will begin when
you press SET in the Set-Point screen.
- To cancel a batch in progress, clear the Set-Point and press SET.
Note: Batch mode operates independently of the desired flow rate, but requires
a non-zero flow rate to run. The rate of flow is determined by the controller
Set-Point value, which is established by the user via analog, front panel or serial
communication methods. Batches can be produced more slowly or more rapidly
as determined by the user-selected Set-Point flow rate.
To turn off Batch Mode: Set the Batch value to zero (0.0) via the front panel or
RS232/RS485 communication using Register 92. If there is a non-zero flow SetPoint, flow will immediately resume, and the Totalizer counter will continue per
the user established Set-Point flow rate.

Omega Portable Meters and Gauges
Omega Rechargeable Flow Meters and Pressure Gauges use a Li-Ion 3.7V cell located in the top
section of the device. The Li-Ion cell must not be removed.
Normal battery life of a fully-charged cell is 18 hours with a monochrome display or
5 hours with a TFT color display, when the backlight is set to 10. Dimming the backlight
will increase battery life.
The battery can be charged through either the micro-USB port or the mini-DIN connector.
When the device is connected to external power it will function normally while the battery
is charging. Note: If the battery has no charge, a charge time of one minute will be required
before the unit can be turned on. Charge rates will be fastest through the micro-USB port
using the included power supply or equivalent. The device will charge fastest when it is
turned off.
Recharge Time: 3.5 hours with 2A USB supply. The micro-USB port is for charging purposes only.
The green/red indicator LED on top of the device will light up green to indicate that the
unit is charging. The green LED will turn off when the battery is charged and the power
switch is turned to “I” for ON.
The indicator LED flashes red when the device has about 1 hour of battery life remaining. The
LED will flash red at a faster rate when the device has about 15 minutes of battery life remaining.
It is highly recommended that the device be charged immediately. When the battery charge runs
out, the display contrast will turn to 0 and device performance is no longer guaranteed.
Output signals from the meter are passed through the mini-DIN connector on top
of the device. Rechargeable battery units do not support 0-10V analog output.
Receiver resistance must be below 250Ω.
Turn the power switch on top of the device to “O” for OFF when it is not in use.
Warning: If the device is left ON until the battery can no longer power it, the
charge indicator will fall out of sync with the actual charge. The device can be
re-synced by fully charging the battery once.

Accessory: FMA1600-MDB Multi-Drop Box
The FMA1600-MDB Multi-Drop Box makes it convenient
to wire multiple flow and/or pressure devices to a single
RS232 or RS485 port. Now available with a USB interface!
The Multi-Drop Box has nine 8 pin mini-DIN ports available.
The ports are to be used with a standard double ended 8 pin
mini-DIN (DC-62) style cable going from the box to each flow or pressure device.
A single DB9 D-SUB type connector (COM PORT) connects, using the included
cable, to the serial connector on a PC or laptop.
All of the flow and/or pressure devices are powered via a terminal block on the
front of the box.
If more than nine devices will be required, additional Multi-Drop Boxes can be
daisy chained together with a double ended 8 pin mini-DIN cable plugged into
any receptacle on both boxes.
FMA1600-MDB Power Supply for Large Valve Controllers: The PS24VHC (Power
Supply 24Vdc High Current) is a 6.5Amp 24Vdc power supply designed for
running multiple large controllers on a FMA1600-MDB.
The 6.5Amp power supply can run as many as 8 large valve controllers, which
makes it ideal for the FMA1600-MDB and multiple large valve (or small valve /
large valve combination) controllers on a FMA1600-MDB.
