  • Description

Application

  • Plastic circular volume flow rate measuring units Type VMRK for the manual or automatic measuring of volume flow rates
  • Suitable for contaminated air
  • Simplified commissioning, approval and maintenance
  • Suitable for permanent installation because of low differential pressure

Special features

  • Measurement accuracy ± 5 % even with unfavourable upstream conditions
  • Effective pressure range: approx. 5 – 250 Pa
  • Low differential pressure of only about  15 – 24 % of the measured effective pressure

Variants

  • VMRK: Volume flow rate measuring unit
  • VMRK-FL: Volume flow rate measuring unit with flanges on both ends

Functional description

The measuring unit is fitted with an effective pressure sensor for measuring the volume flow rate.

The effective pressure is either measured and evaluated manually, or transformed into an electric signal by a pressure transducer.

 

Plastic (PPs) circular volume flow rate measuring unit for the measurement of volume flow rates in air conditioning systems, available in 6 nominal sizes.

For the manual volume flow rate measuring or for the permanent monitoring of the actual value signal.

Ready-to-commission unit which consists of the casing with an averaging differential pressure sensor.

Spigot, suitable for ducts according to DIN 8077.

Casing air leakage to EN 15727, class C.

Special features

  • Measurement accuracy ± 5 % even with unfavourable upstream conditions
  • Effective pressure range: approx. 5 – 250 Pa
  • Low differential pressure of only about  15 – 24 % of the measured effective pressure

Materials and surfaces

  • Casing made of flame-resistant polypropylene (PPs)
  • Differential pressure sensor made of polypropylene (PP)

Technical data

  • Nominal sizes: 125 – 400 mm
  • Volume flow rate range: 25 to 1680 l/s or 90 to 6048 m³/h
  • Effective pressure range: approx. 5 – 250 Pa
