PRODUCTS / Flow Meter / VD 500 - Flow sensor for wet compressed air

VD 500 - Flow sensor for wet compressed air

Add to enquiry

Reduce your energy costs and increase your efficiency with the VD 500. Suitable directly for measurement after the compressor. Monitor the delivery rate of your compressor and create a FAD analysis.

Field of application:

  • Measurement immediately downstream of the compressor
  • Measurement at high temperatures

Advantages of the differential pressure sensor VD 500:

  • New: Unique sensitivity in the lower measuring range: Measures from as little as 2 m/s and thus covers the complete operating range of variable speed drive (VSD) compressors
  • Particularly suitable for extremely high flow rates
  • Flow, total consumption, temperature and pressure
  • Measurement at high temperatures, max. temperature 180 °C
  • Can be used in pipes from DN 20 to DN 600
  • Installation via 1/2″ ball valve under pressure

Typical applications:

  • Measurement of the capacity of compressors
  • Compressed air audits
  • Efficiency measurement of compressed air systems

Installation conditions:

  • After functioning water separator
  • In horizontal lines (recommended) or in risers

Technical details:

  • 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard
  • Optional interfaces like Modbus TCP (Ethernet), PoE, M-Bus 
  • Pressure range up to 30 bar 
  • Temperature of the medium -30 ° ... +180 °C
  • Integrated display to show the measured values 
  • Available from DN20 to DN500
  • Easy installation under pressure
  • Settings adjustable via the keys of the display
  • Main counter reading can be reset via the display 
  • Can be used for velocities up to 600 Nm/s
  • High accuracy with 1.5% deviation of the measured value
