The FMA-1600A Series mass and volumetric Omega's flow meters use the principle of differential pressure within a laminar flow field to determine the mass flow rate. A laminar flow element (LFD) insdie the meter forces the gas into laminar (streamlined) flow. Inside this region, the Poiseuille equation dictates that the volumetric flow rate be linearly related to the pressure drop along a fixed distance of the LFE. This, along with the viscosity of the gas, is used to accurately determine the volumetri flow rate. Separate absolute temperature and pressure sensors are incorporated and correct the volumetric flow rate to a set of standard conditions. This standardized flow rate is commonly called the mass flow rate and is reported in units such as standard cubic feet per minute (SCFM) or standard liters per minute (SLM).
Standard units include a 0 to 5 V output (4 to 20 mA optional) and RS232 communications. The gas select feature can be adjusted from the front of the keypad or via RS232 communications. Volumetric flow, mass flow, or absolute pressure, and temperature can be viewed or recorded through the RS232 connection. It is also possible to multi-drop up to 26 units on the same serial connection to a distance of 125'. These flowmeters are also available in a portable version for use in the field (-B models).

Good Mass Flowmeter
Easy to setup and reliable. Easy to use. Remote operation needs expert installation but is easy to use after setup. Price could be lower to have a broader application.

Very Dependable Unit
These units are very dependable. Have bought them on several occasions. Omega also has a good return policy which I had used because I had mistakenly bought the wrong unit. It was very painless to get it sent back and order the correct one.

hi how i can connect it to o2 generator @65 psi thank you
Good Afternoon,
Intended to read Air flow, does the display can be selected to show the flow in PPH?
Date published: 2021-05-06
How do I connect the device to a PC/laptop? What accessories are needed and what software?
Thank you for your inquiry! These units come standard with RS232 communications which will be the means for connecting to a PC or laptop. This will require a serial cable and Hyperterminal program mentioned on page 26 of the product manual.

Can the FMA-1612A be used in vacuum systems with air? Do you have CAD files (ideally Inventor) of the meter's external dimensions?
Thank you for your inquiry! Yes, the FMA-1612A can be used in vacuum systems. Unfortunately, we do not have any 3D models for this device. All available dimensions will be listed in the product manual for this unit.

Intended to read air flow, can the display be set up to read in PPM?
Thank you for your inquiry about the mass flow meter. Unfortunately, it does not have the ability to read in concentration, only volumetric and true mass flow rates.
Date published: 2021-05-07
Item# FMA-1621A-I2- I would like to purchase this, can you verify how many decimals places the readout will be. I see the range is 0 to 1500SLPM. I need at least one decimal places. How many decimal places are the readings?
Thank you for your inquiry about the mass flow mter. The display will have 2 decimal places when measuring the flow rate.

Hello, If our desired maximum flow rate is 3000 SLM but pressure is 100 psi (actual LM much lower), is this still the correct instrument to buy? Is the 0.8% accuracy relative to the maximum flow rate or is it a % of the flow rat being read?
Thank you for your inquiry about the mass flow meter. Yes, this series has a flwo meter with a maximum flow capacity of 3000 LPM and the accuracy is percent flow rate reading, not of full scale in other mass flow meters.

I have a problem with an FMA-16018A sensor. I want to use RS232 communication, but I can't find the messages I need to send to receive the measurement data. I can only get it to send me data when it´s in straming mode.
Thank you for your inquiry about the mass flow meter. Please send an email to flow@omega.com along with the serial number and advise what information you wish to retrieve via RS232 communication and can provide the information.
Date published: 2022-02-23
Hello, does this meter read total mass or volume con the LCD screen?
Thank you for your inquiry about this flow meter. You can have the display read in true mass flow, if you need a totalizer, that is an option, ('-TOT'), which will be in total mass.
