Differential pressure metering orifices

for thermoprocessing equipment

These differential air pressure metering orifices in sizes LRM 40 to LRM 125 are designed to build up a pressure differential in combustion air lines.
Metering orifices can be mounted in any orientation.

Rugged aluminium body with G¼“ threaded ports on all
4 sides for connection of optional accessories:

  • differential pressure sensors
  • pressure switches
  • vertical pressure gauges (Wiedemann VHM….)

Metal sealing system, self-centering orifice plate labelled with text. Each orifice plate is calculated per customer specifications and is produced in-house.

  • volumetric flow rate range: 40-1400 mN³/h
  • common pressure differential: 18-25 mbar
