VPFlowScope DP Thermal Mass Flow Meter

VPFlowScope DP Thermal Mass Flow Meter for wet and dirty compressed air

The VPFlowScope® DP measures mass flow, temperature and pressure simultaneously and is optimized for hot, saturated compressed air measurements. The patented design has a bright blue LCD display which provides real-time information that, in combination with the built-in data logger, enables you to make recordings for certain periods of time. In turn, you can use our VPStudio software to process this data and print reports for real-time measurements.

Features and benefits 

  • For saturated compressed air
  • Four sensors in one instrument
  • Standard Modbus and 4 … 20 mA
  • Bi-directional flow measurements


  • Air audits
  • Compressor efficiency monitoring
  • Air treatment equipment (drier/filter) monitoring
