DFP Mass Flow Transducer
Pressure Compensated Flow Transducer
  • F-Series with Digital Display
  • Real time mass flow measurement can be used for active flow control
  • Differential pressure technology
  • < 10 ms response time
  • Flow ranges up to 250 SCFM & as low as 20 SCFH

  • Cost effective

The DFP flow transducer is a pressure compensated mass flow transducer with a digital display.  The operating pressure of the compressed gas is measured and the flow transducer output is compensated for the change in gas density due to pressure.   Differential pressure technology 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 transducer where real time flow measurement is critical to a process. Analog outputs of 0-10Vdc and 4-20mA are available. Flow transducer 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.
