Orifice flow plate for liquid, gases and steam
- Pressure loss depends upon diameter ratio β (d/D) and amounts to ca. 30 - 80%
- Measuring uncertainty: 0,5% - 1,2% of the discharge coefficient
Fields of application
- Flow measurement of liquid, gases and steam in pipes for nominal sizes up to 40”
Orifice plate with welded-on handle for direct installation between flanges for flow measurement. Depending on the process conditions, the plate type may be manufactured as square edged concentric, quarter circle nozzle, segmental, plate with conical entrance and double cone. Pressure taps may be positioned in the flange blade or in the pipeline. Orifice flanges are manufactured according to ASME B16.36 or DIN 19214.
