Thermal Mass Flow Meter for Compressed Air and Gases VA 520
VA 520 is integrated, precise differential pressure sensor measures the differential pressure/ dynamic pressure at the sensor tip. The pressure depends on the respective gas velocity. The flow is therefore easy to determine by means of the pipe diameter. The additional measurement of temperature and absolute pressure and calculation of the relevant density means that measuring can be carried out for various gases, a wide variety of temperatures and pressures.

Benefits at a glance:
- Measurement of mass flow rate, output of standard volume flow rate
- High accuracy for both small and large flows
- Pressure and temperature compensated by the thermal mass flow principle
- Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
- No moving parts, therefore low maintenance
- Vanishingly low pressure loss due to vanishingly low blockage of the diameter
- Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.
