F-Series Mass Flow Transducer

Brand: Proportion-Air, Inc

The F-series Mass Flow Transducer is a fast response flow monitor for all noble gases.

The F-series uses a differential pressure measurement of air flowing across an internal Venturi. The analog electronic circuit converts the differential pressure to an electronic output that is linear to the mass flow rate of air passing through the Venturi.

The combination of differential pressure with analog electronics makes for a fast response flow measurement.

The F-series mass flow transducer may be coupled to a variety of Proportion-Air electronic flow control valves to make a complete factory calibrated flow control package.
