Product Description Order No.
VA 520 flow meter with 3/4" measuring section    0695 1522
VA 520 flow meter with 1" measuring section    0695 1523
VA 520 flow meter with 1 1/2" measuring section    0695 1524
VA 520 flow meter with 2" measuring section   0695 1525

Advantages of the VA 520 flow meter:
  • 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.
