Some fuel cell units and other applications may require very accurate measurement and/or control of gas flow. 

This can be done with an MFC (mass flow controller). An MFC will measure the flow of gas, as well as control the flow when set up with attendant circuitry. The particular model shown in the photo has a 0-5 input/output and is powered by 15 volt DC source. It has a maximum operating pressure of 1500 psi and the valve is NC (normally closed).
