The FMA5400A/5500A mass flow controllers feature a built-in normally-closed electromagnetic valve for maintaining a constant flowrate regardless of variations in inlet or outlet pressures. The setpoint is controlled either locally via a potentiometer accessible through an access window in the case or remotely via an analog 0-5 Vdc or 4-20 mA signal (field selectable). The FMA5400A/5500A series require 12 to 26 Vdc power @ 800 mA maximum, which can be supplied by the FMA545PW wall plug-in socket power supply. 12 to 15 Vdc power @ 800 mA maximum (Sizes 43,44, and 45 ONLY). Model number FMA545C (supplied separately) provides a mating 15-pin “D” connector with 8 feet of shielded cable for accessing the analog output signals and power input connections. The LCD supplied with the FMA5500A series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assembly–you must then build your own assembly for panel mounting the LCD.

You get what you pay for
Works exactly as expected, like all Omega products.

Mass flow controller
It works great, very sensitive. Seller should provide a adapter with controllers to run

Love them
Great MFCs at a quick turn around, we use them in many applications. Some times in multiple flows.

Difficult to work with and incomplete manual
Mass flow controller is not functional with shop air.

Does the FMA5400A/5500A both measure and control flow rate? Or will I need two separate products?
Thank you for your inquiry for the mass flow controller. First, it is advised to use as a controller to control the gas and can be used as a flow meter, in the event that you do not have the means to measure flow rate only. You can use the override Purge on PINS 3 & 4 for 15 minutes at a time and this is due to the cylinder becoming hot and needs to cool down to the touch.

I have an FMA5508A-ST MFC with me and I have used it with many gases like Ar, He, etc. I wanted to know is it compatible with water vapors? I wanted to use around 10% water vapor in Ar for my experiments. Thanks in advance.
Thank you for your inquiry about the MFC. Unfortunately, the MFC work best with clean, dry gases and can sustain relative humidity, non-condensing gases, up to 70%.

We required Flow controllers for Methane gas & flow is 34LPM & second one for Propane gas 350 Liter per hours. Kindly suggest us your best module for the same.
Thank you for your inquiry about the mass fow controllers. It would be recommended to use the FMA5528A for methane gas and FMA5520A for propane gas and will need to create a customized part number for the flow controllers mentioned and then, have it loaded onto the web site to prepare a quote.

I want to know the educational prices of the machine OMEGA FMA5502A
Thank you for your inquiry. Please email your request to sales@omega.com

Hello, I'm looking for a flow controller that can handle flows (CO/Nitrogen mix) of around 200-300 ml/min with an accuracy of plus/minus 2%. Can you suggest something ?
Thank you for your inquiry. The FMA5512A is the controller that will fit the flow range and can have it calibrated specifically for the percentage mixture of gas by weight or by volume. Please note that in the event the composition changes during the reaction, the controller is not able to compensate for the changes that occurr.

I need to set flow rates, but I don't see a way to key in my settings, so how exactly this works? I have a FMA5518A-C
Thank you for your inquiry! The flow rate can be controlled through either locally or remotely depending on preference. Local control requires the use of the local set point potentiometer on the back of the unit. For remote control 0-5 VDC or 4-20 mA reference signals will be needed to adjust the flow.

I have FMA5502A on hand but there is no instructions on how to use the potentiostat on the back to adjust the flow rate, or set the identity of the gas (we want to use this for CO2). Do you have detailed instructions on this?
Thank you for your inquiry about the MFC. If manually controlling the flow via the potenitometer, clock-wise turn is increasing the flow rate and counter clock-wise would decrease the flow rate and it may take a number of 360 degree turns to reach the desire flow via the LCD display. The manual has a chart listing a number of different gases that can be used to control and along with a K-factor associated to multiply against the flow rate on the LCD that will account for that specific gas.
