Differential pressure primary element with industry-related documents, certifications and tests
- Equipment of complete measuring points incl. differential pressure transmitters, temperature and pressure transmitters and flow computer
- Hydrostatic pressure test, dye penetration procedure, x-ray and ultrasound test, PMI
- Comprehensive test and certification documentation
Different primary elements are available for differential pressure flow measurement of aggressive and non-aggressive gases, vapour and liquids:
Orifice plates
- With positioned grip plate for direct installation between pipe or measuring flanges
- Available as a standard orifice plate, quarter circle nozzle, segmental orifice plate, orifice plate with conical inlet, double cone orifice plate
- In particular for large line sizes
Compact or integral orifice plates
- Like orifice plates, but with a carrier ring for differential pressure pipes: Installation possible between normal pipe flanges
- Pressure taps via single bore or annular chamber
Orifice plate with flange tapping
- Like orifice plates, but with measuring flanges: Pressure is removed via a boring in the flange respectively in the defined distance before or after the orifice plate disc
- Measuring flanges as standard according to ASME B 16.36 or DIN 19214, other standards are possible
Meter runs
- Primary elements combined with an inlet and outlet section for low-disturbance flow measurement; they are frequently used in small pipes as the impact of disturbance factors is greatest there
- Supplied completely assembled and ready for installation, with flange or weld in connection
- Numerous versions are available
Nozzles
- Primary elements with lower pressure loss compared to the orifice plate
Restricting orifice plates
- For defined pressure destruction in the process, or in air outlet pipes
- For all single-phase media
- As a simple blank with a welded-on handle for installation between pipe flange or as a welded-in variant
- Hardening of the restricting boring with certain materials possible for a longer lifespan
