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
