MOUNTING

FMA-1600A Gas Flow Meters have holes on the bottom for mounting to flat panels. See pages 47-60.

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 38-51.

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 specifi ed below is required to use the power jack.

Meters require a 7-30 Vdc power supply with a 2.1 mm female positi ve center plug capable of supplying at least 100mA.

Note: 4-20mA analog output requires at least 15 Vdc.

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 refl ects the system bus voltage and can be used as a source for the set-point signal.

For DB15 Pin-outs, see pages 62 to 67.

INPUT SIGNALS

Analog Input Signal

Apply analog input to Pin 4 as shown on page 8.

For DB15 Pin-outs, see pages 62 to 67.

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.

Opti onal 0-10 Vdc: If specifi ed at ti me of order, a 0-10 Vdc input signal can be applied to pin 4, with common ground on pin 8.

Opti onal 4-20 mA: If specifi ed at ti me 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 essenti ally a

250 ohm resistor to ground.

NOTE: 4-20 mA output requires at least 15 Vdc power input.

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 25 for details on accessing RS232 / RS485 output.)

Standard Voltage (0-5 Vdc) Output Signal

FMA-1600A fl ow meters equipped with a 0-5 Vdc (opti onal 0-10 Vdc) will have this output signal available on Pin 6. This output is generally available in additi on to other opti onally ordered outputs. This voltage is usually in the range of 0.010 Vdc for zero fl ow and 5.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.

Opti onal 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 Calibrati on 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 fl ow and 10.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.

Opti onal 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 Calibrati on Data Sheet that shipped with your meter to determine which output signals were ordered.) The current signal is 4 mA at

0 fl ow and 20 mA at the meter’s full scale fl ow. The output current is linear over the enti re range. Ground for this signal is common on Pin 8. (Current output units require 15-30Vdc power.)

Opti onal 2nd Analog Output Signal

You may specify an opti onal 2nd analog output on Pin 2 at ti me of order. (See the Calibrati on 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 opti onal output, a meter could output the mass fl ow rate (0-5 Vdc on pin 6) and the absolute pressure (0-5 Vdc on pin 2).

Gas Absolute Pressure: This sensor references hard vacuum and reads incoming pressure both above and below local atmospheric pressure. This parameter is moved to the primary display by pushing the button above PSIA.

The engineering unit associated with absolute pressure is pounds per square inch absolute (psia). This can be converted to gage pressure (psig) by subtracting local atmospheric pressure from the absolute pressure reading:

PSIG = PSIA – (Local Atmospheric Pressure)

Pushing the button again allows you to select 0C (Celsius), 0K (Kelvin), 0F (Fahrenheit) or 0R (Rankine) for the temperature scale.

To select a temperature scale, use the UP and DOWN 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.

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

15

when removed from the line and blocked, it was given a false zero. It is bett er to zero the unit at atmospheric pressure and a confi rmed no fl ow conditi on 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 butt on below CCM in this example. Your display may show a diff erent unit of measure.

Mass Flow Rate: The mass fl ow rate is the volumetric fl ow rate corrected to a standard temperature and pressure (typically 14.696 psia and 25 °C).

This parameter is located in the lower middle of the display. It can be moved to the primary display by pushing the butt on below SCCM in this example. Your display may show a diff erent unit of measure preceded by the lett er S.

To get an accurate volumetric or mass fl ow 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) fl ashes when a measured parameter exceeds the range of the sensor. When any item fl ashes, neither the fl ashing parameter nor the mass fl ow measurement is accurate. Reducing the value of the fl ashing parameter to within specifi ed limits will return the unit to normal operati on and accuracy.

If the unit does not return to normal operati on contact Omega.

RS232 / RS485 Output and Input

Configuring HyperTerminal®:

1. Open your HyperTerminal® RS232 / RS485 terminal program (installed under the “Accessories” menu on all Microsoft Windows® operating systems).

2. Select “Properties” from the file menu.

3. 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.

4. Under the “Settings” tab, make sure the Terminal Emulation is set to ANSI or Auto Detect.

5. 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.

6. 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”.

25

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$$V<Enter> (e.g. B$$V<Enter>)

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.

26

Gas Select – The selected gas can be changed via RS232 / RS485 input. To change the selected gas, enter the following commands:

In Polling Mode: Address$$#<Enter> (e.g. B$$#<Enter>)

Where # is the number of the gas selected from the table below. Note that this also corresponds to the gas select menu on the flow meter screen (the Standard gas category is shown in the example below):

Creating and Deleting Gas Mixtures with Composer using RS232 or RS485

Note: All commands must be prefixed with the unit ID if the unit is not in streaming mode.

You may create and store up to 20 gas mixtures containing up to five constituent gases each.

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] …

Gas Name: Name your mixture using a maximum of 6 characters.

Gas Mix Number: Composer user mixes have 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 gas number of the first constituent gas.

Percent 2: The percentage of the first constituent gas. Values entered beyond two decimal points will be rounded to the nearest 0.01%.

Gas Number 2: The gas number of the first constituent gas.

Additional Gases: (Optional) The above pattern of [Percent] + [Gas Number] may be repeated for additional constituent gases up to a total of 5 constituents.

The sum of all percentages must be 100.00.

On 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 is not successfully mixed, a "?" is returned.

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 "?" is returned.

28

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® 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 page 30.

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 °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®

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.

13. Click on the “ASCII Setup” button.

30

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 47-56) 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° 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.

40

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® and reopen it. Reboot your PC. See pages 10, 11 and 25 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 3.2% of full scale. See page 22.

Discrepancies between old and new units.

Please see “Standard Gas Data Tables” explanation on page 31.

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 24).

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.

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.

Rollover – The customer can also specify at the time of order what the totalizer is to do when the maximum count is reached. The following options may be specified:

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.

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$$T <Enter> (e.g. B$$T <Enter>)

Omega Portable Meters and Gauges

Omega Rechargeable Flow Meters and Pressure Gauges use a Li-Ion 3.7V cell located in the top secti on of the device. The Li-Ion cell must not be removed.

Normal batt ery 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 batt ery life.

The batt ery can be charged through either the micro-USB port or the mini-DIN connector.

When the device is connected to external power it will functi on normally while the batt ery is charging. Note: If the batt ery has no charge, a charge ti me 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 batt ery is charged and the power switch is turned to “I” for ON.

The indicator LED fl ashes red when the device has about 1 hour of batt ery life remaining. The

LED will fl ash red at a faster rate when the device has about 15 minutes of batt ery life remaining.

It is highly recommended that the device be charged immediately. When the batt ery 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 batt ery 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 unti l the batt ery 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 batt ery once.

A Batt ery Charge Indicator appears below Tare on the display:

Accessory: FMA1600-MDB Multi -Drop Box

The FMA1600-MDB Multi -Drop Box makes it convenient to wire multi ple fl ow 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 fl ow 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 fl ow and/or pressure devices are powered via a terminal block on the front of the box.

If more than nine devices will be required, additi onal 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 multi ple 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 multi ple large valve (or small valve / large valve combinati on) controllers on a FMA1600-MDB.
