FA Air Flow Meter-Image

The FA flow monitor is a flow to atmosphere mass flow transducer which provides flow measurement in real time, less than 10ms. There are no moving parts and it is immune to vibration. It is an ideal flow monitoring device where real time flow measurement is critical to a process. Analog outputs of 0-10Vdc and 4-20mA are available. Flow output ranges up to 250 SCFM and as low as 20 SCFH. It can be teamed up with a Proportion-Air flow controller for closed loop flow control.\
