The innovative MASS-VIEW® mass flow meter series are a digital alternative to the conventional VA meters (variable area meters) or purge meters
The MASS-VIEW® mass flow meter series incorporates a digital bar graph of actual gas flow, which is, thanks to the OLED (organic light emitting diode) technology, clearly visible from all angles, as well as indicating flow units, gas type and totalised figures. 

The MASS-VIEW series is designed to mimic the straightforward features and vertical format of the VA meter/ball meter, but with the considerable added benefits of an electronic output signal, high measuring accuracy, virtual independence from gas temperature and pressure variations, freedom from parallax error and inherently safe construction, by eliminating fragile glass components in the flow path. 


  • Clear indication in:
    • actual flow rate (bar graph and value)
    • desired flow units
    • type of gas 
    • totalized flow
  • Bright, wide-angle OLED display
  • Free of parallax errors
  • Virtually independent of pressure and temperature variations
  • Low pressure drop
  • Wide flow ranges
  • Fast response
  • High accuracy
  • Alarm and counter functions (2 alarm contacts available on meters)
  • Analog (0..5 Vdc) and digital communication (Modbus-RTU/ASCII, RS-232 interface)
  • Configurable password protection
  • 10 pre-installed gases available (Air, N2, O2, Ar, CO, CO2, CH4, C3H8, C4H10, N2O) or H2 or He
  • 4 selectable ranges (100%, 50%, 25% and 10% of maximum full scale range)
  • Digitally calibrated
