MOUNTING
FMA-1600A Gas Flow Meters have holes on the bottom for mounting to flat
panels. See pages 51-65.
FMA-1600A Meters can usually be mounted in any position.
No straight runs of pipe are required upstream or downstream of the meter.
PLUMBING
Your meter 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 gas will flow in the direction indicated by the flow arrow.
Standard FMA-1600A Gas Flow Meters 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 51-65.
Meters 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 meter should they get
into the flow stream.
6
We recommend the use of in-line sintered filters to prevent large
particulates from entering the measurement head of the instrument.
Suggested maximum particulate sizes are as follows:
5 microns for units with FS flow ranges of 0-1 sccm or less.
20 microns for units with FS flow ranges between 0-2 sccm and 0-1 slpm.
50 microns for units with FS flow ranges of 0-1 slpm or more.
PRESSURE
Maximum operating line pressure for FMA-1600A units is 145 psig (1 MPa).
If the line pressure is higher than 145 psig (1 MPa), use a pressure regulator
upstream from the flow meter to reduce the pressure to 145 psig (1 MPa) or less.
Maximum operating line pressure for FMA-LP1600A units is 50 psig.
Exceeding the maximum specified line pressure may cause permanent
damage to the solid-state differential pressure sensor.
Do Not subject an FMA-1600A Differential Pressure sensor to
upstream-downstream pressure differentials exceeding 75 PSID.
Do Not subject a FMA-LP1600A Differential Pressure sensor to
upstream-downstream pressure differentials exceeding 15 PSID.
While high static pressure will typically not damage the dp sensor, sudden
pressure “spikes” can result in complete failure of the sensor.
A common cause of this problem is instantaneous application of
high‑pressure gas as from a snap acting solenoid valve either upstream
or downstream of the meter. If you suspect that your pressure sensor is
damaged please discontinue use of the meter and contact Omega.
7
POWER AND SIGNAL CONNECTIONS
Power can be supplied to your meter 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.
Meters require a 7-30 Vdc power supply with a 2.1 mm female positive center
plug capable of supplying at least 100mA.
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 67 to 73.
8
INPUT SIGNALS
Analog Input Signal
Apply analog input to Pin 4 as shown on page 8.
For DB15 Pin‑outs, see pages 67 to 73.
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: 4-20 mA 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.

A remote tare can be achieved by momentarily grounding pin 4 to tare
as shown above.

RS232 / RS485 Digital Input Signal
To use the RS232 or RS485 input signal, 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 below. (See page 26 for details on accessing

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 26 for
details on accessing RS232 / RS485 output.)
Standard Voltage (0-5 Vdc) Output Signal
FMA-1600A flow meters 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 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 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 15-30Vdc 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 mass flow rate (0-5 Vdc on pin 6) and
the absolute pressure (0-5 Vdc on pin 2).
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.

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.
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
15
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.
Volumetric Flow Rate: This parameter is located in the lower left of the display.
It is moved to the primary display by pushing the button below CCM in this
example. Your display may show a different unit of measure.
Mass Flow Rate: The mass flow rate is the volumetric flow rate corrected to a
standard temperature and pressure (typically 14.696 psia and 25 &deg;C).
This parameter is located in the lower middle of the display. It can be moved to
the primary display by pushing the button below SCCM in this example. Your
display may show a different unit of measure preceded by the letter S.
To get an accurate volumetric or mass flow rate, the gas being measured
must be selected. See Gas Select, page 18.
MENU: Pressing MENU switches the screen to the Select Menu display.
Flashing Error Message: An error message (MOV = mass overrange,
VOV = volumetric overrange, POV = pressure overrange, TOV =
temperature overrange) flashes when a measured parameter exceeds
the range of the sensor. When any item flashes, neither the flashing
parameter nor the mass 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 operation contact Omega.

5.
6.
Open your HyperTerminal&reg; RS232 / RS485 terminal program (installed under
the “Accessories” menu on all Microsoft Windows&reg; 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&reg; 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”.
26
Tareing via RS232 / RS485:
Tare –Tareing (or zeroing) the flow meter provides it with a reference point for
zero flow. This is a simple but important step in obtaining accurate measurements.
It is good practice to “zero” the flow meter each time it is powered up. A unit may
be Tared by following the instructions on page 10 or it may be Tared via RS232 /
RS485 input.
To send a Tare command via RS232 / RS485, enter the following strings:
In Polling Mode: Address$$V&lt;Enter&gt;
(e.g. B$$V&lt;Enter&gt;)
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.

Gas Select – The selected gas can be changed via RS232 / RS485 input. To change

Creating and Deleting Gas Mixtures with Composer using RS232 or RS485
Note: All commands must be prefixed with the unit ID letter. The unit should
not be in streaming mode.
You may create and store up to 20 gas mixtures containing up to five
constituent gases each. The constituent gases must be chosen from the existing
list of gases installed on the device (which may vary model to model). Please
see pages 33 – 40 for lists of gases and their corresponding gas numbers.
Create a Gas Mixture
To create a gas mixture, enter a single-line command according to the following formula:
[Unit ID] GM [Gas Name] [Gas Mix Number] [Percent 1] [Gas Number 1]
[Percent 2] [Gas Number 2] …etc. etc.
Notes: Do not type the brackets. There should be only one space between
all items. Any percentages less than 1, should have a leading zero before
the decimal (i.e. 0.25 for .25%). Trailing zeros are not necessary but they are
allowed to help visualize the percentages on screen (as in the example). The
sum of all percentages must be 100.00 otherwise an error will occur.
Here is an example of a three gas mixture for a new gas called “MyMix1”
(50% O2, 49.5% Helium, and .5% Neon), stored in user location #236, where the
unit ID of the device is “A”:
A GM MyMix1 236 50.00 11 49.50 7 0.50 10
&lt;ENTER&gt;
Gas Name: Name your mixture using a maximum of 6 characters.
Gas Mix Number: Composer user mixes have Omega gas numbers between
236 and 255. You can assign any number in this range to your new mixture. If
another mixture with the same number exists, it will be overwritten, even if
that gas is currently selected on the unit. If you enter a 0 here, the new mix
will be assigned the next available number between 236 and 255.
Percent 1: The percentage of the first constituent gas. The percentage of each
constituent must be between 0.01 and 99.99. Values entered beyond two
decimal points will be rounded to the nearest 0.01%.
Gas Number 1: The Omega gas number of the first constituent gas.
Percent 2: The percentage of the second constituent gas. Values entered
beyond two decimal points will be rounded to the nearest 0.01%.
Gas Number 2: The Omega gas number of the second constituent gas.
Additional Gases: (Optional) The above pattern of [Percent] + [Gas Number]
may be repeated for additional constituent gases (up to a total of five).
Upon success, the unit ID (if set) is returned followed by a space. The number
of the gas mixture is then returned, followed by the percentages and names
of each constituent in the mix. If the gas mix is not successfully created, a &quot;?&quot;
is returned, and you must start over.
Delete a Gas Mixture
To delete a gas mixture, enter:
[Unit ID]GD [Gas Number]: The number of the Composer user mixture you
wish to delete from the unit
Only Composer user mixtures can be deleted with this command.
On success, the unit ID (if set) is returned followed by a space and the number of
the gas deleted. If the gas is not successfully deleted, a &quot;?&quot; is returned.

Collecting Data:
The RS232/RS485 output updates to the screen many times per second. Very shortterm events can be captured simply by disconnecting (there are two telephone
symbol icons at the top of the HyperTerminal&reg; 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&reg; Excel&reg; 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&reg; or from
a text file can be pasted directly into Excel&reg;. When the data is pasted it will all
be in the selected column. Select “Text to Columns...” under the Data menu in
Excel&reg; 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 page 31.
Data Format:
The data stream on the screen represents the flow parameters of the main mode
in the units shown on the display.
For mass flow meters, there are five columns of data representing pressure,
temperature, volumetric flow, mass flow and the selected gas.
The first column is absolute pressure (normally in psia), the second column is
temperature (normally in &deg;C), the third column is volumetric flow rate (in the
units specified at time of order and shown on the display), and the fourth column
is mass flow (also in the units specified at time of order and shown on the
display). For instance, if the meter was ordered in units of scfm, the display on
the meter would read 2.004 scfm and the last two columns of the output below
would represent volumetric flow and mass flow in cfm and scfm respectively.

Sending a Simple Script File to HyperTerminal&reg;
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&reg; and a text editing program such as Microsoft&reg;
Word&reg; 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&lt;Enter&gt; 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&lt;Enter&gt;, 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.
13. Click on the “ASCII Setup” button.
31
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.
Operating Principle
All FMA-1600A Gas Flow Meters and FMA-2600A Gas Flow Controllers are based
on the accurate measurement of volumetric flow. The volumetric flow rate is
determined 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 gas 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.
STANDARD GAS DATA TABLES: Those of you who have older Omega products
may notice small discrepancies between the gas property tables of your old and
new units. Omega has incorporated the latest data sets from NIST (including
their REFPROP 9 data where available) in our products’ built-in gas property
models. Be aware that the calibrators that you may be using may be checking
against older data sets such as the widely distributed Air Liquide data. This may
generate apparent calibration discrepancies of up to 0.6% of reading on well
behaved gases and as much as 3% of reading on some gases such as propane and
butane, unless the standard was directly calibrated on the gas in question.
As the older standards are phased out, this difference in readings will cease
to be a problem. If you see a difference between the Omega meter and your
in-house standard, in addition to calling Omega, call the manufacturer of your
standard for clarification as to which data set they used in their calibration. This
comparison will in all likelihood resolve the problem.

TROUBLESHOOTING
Display does not come on or is weak.
Check power and ground connections. Please reference the technical
specifications (pages 51-61) 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. Avoid installations that can
subject sensor to pressure drops in excess of 10 psid. A common cause of this
problem is instantaneous application of high‑pressure gas 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 meter and contact Omega.
Displayed mass flow, volumetric flow, pressure or temperature is flashing and
message MOV, VOV, POV or TOV is displayed:
Our flow meters and controllers display an error message (MOV = mass
overrange, 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 mass 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, but not to the full scale flow rate
(it is not calibrated for bi-directional flow) and no damage will result.
Meter does not agree with another meter I have in line.
Volumetric meters are affected by pressure drops. Volumetric flow meters
should not be compared to mass flow meters. Mass flow meters can be
compared against one another provided there are no leaks between the two
meters and they are set to the same standard temperature and pressure. Both
meters must also be calibrated (or set) for the gas being measured. FMA-1600A
mass flow meters are normally set to Standard Temperature and Pressure
conditions of 25&deg; C and 14.696 psia. Note: it is possible to special order meters
with a customer specified set of standard conditions. The calibration sheet
provided with each meter lists its standard conditions.
When performing this comparison it is best to use the smallest transition
possible between the two devices. Using small transitions will minimize lag and
dead volume.
43
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: FMA-1600A meters feature a programmable geometric running average (GRA)
that can aid in allowing a rapidly fluctuating flow to be read (see “Pressure Averaging”
and “Flow Averaging” page 22).
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.
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 instructions in this manual (Check
the RS232 / RS485 communications select screen for current meter readings).
Close Hyperterminal&reg; and reopen it. Reboot your PC. See pages 10, 11 and 26
for more information on RS232 / RS485 signals and communications.
Slower response than specified.
FMA-1600A Meters 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 22.
Jumps to zero at low flow.
FMA-1600A Meters 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 22.
Discrepancies between old and new units.
Please see “Standard Gas Data Tables” explanation on page 32.
44
Maintenance and Recalibration
General: FMA-1600A Flow Meters require minimal maintenance. They have no
moving parts. The single most important thing that affects the life and accuracy
of these devices is the quality of the gas being measured. The meter is designed
to measure CLEAN, DRY, NON-CORROSIVE gases.
Moisture, oil and other contaminants can affect the laminar flow elements.
We recommend the use of in-line sintered filters to prevent large particulates
from entering the measurement head of the instrument. Suggested maximum
particulate sizes are as follows:
5 microns for units with FS flow ranges of 0-1 sccm or less.
20 microns for units with FS flow ranges between 0-2 sccm and 0-1 slpm.
50 microns for units with FS flow ranges of 0-1 slpm or more.
Recalibration: The recommended period for recalibration is once every year.
A label located on the back of the meter lists the most recent calibration date.
The meter 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 display (page 25).
Cleaning: FMA-1600A Flow Meters 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 repairs, recalibrations, or recycling of this product, contact Omega.
45
Option: Totalizing Mode
Meters and Controllers can be purchased with the Totalizing Mode option. 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
SCCM

button will cycle the large numbers on the
display between total mass and time elapsed.
Rollover – The customer can also specify at the
SCCM
time of order what the totalizer is to do when
0000:00:00
the maximum count is reached. The following
options may be specified:
BACK
RESET
MENU
No Rollover – When the counter reaches the
maximum count it stops counting until the
counter is cleared.
Rollover – When the counter reaches the maximum count it automatically rolls
over to zero and continues counting until the counter is cleared.
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.
00000.00
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
ELAPSED TIME to show this as the primary display.
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 RS232 or RS485 section of the
manual. To reset the counter, enter the following commands:
In Polling (addressable) Mode: Address$$T &lt;Enter&gt; (e.g. B$$T &lt;Enter&gt;)

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.

The following pin-out chart describes the safest and generally compatible arrangement when
connecting a non-FMA-1600A DB15 wire to a DB15B equipped FMA-1600A. Not all features
may be available between brands, but the common denominators are featured in our DB15
offerings, along with some options for customization.
