The S431 OEM Pitot Tube Compressor Flow Meter (Inline) is designed to
measure the air delivery of a compressor. It can be installed at the
discharge side inside the compressor where wet and contaminated air
occurs.
The S431 can measure the following parameters for compressed air or
gases:
Parameter Default unit
Actual velocity m/s
Volumetric flow m3/h
Pressure bar
Total consumption m3
Temperature °C
5 Features
•Measurement of flow, pressure, and temperature at the
compressor outlet
•Measurement of wet air and air at high temperatures
•Calculation of total consumption
•No straight piping required, - if the S431 is calibrated on the
compressor test bench
•Easy to install on welding nipples
•Rugged design for harsh environment: ambient temperatures up
to 90°C, vibration proof
•No mechanical wear parts
•One flow meter for DN50 ... DN900
