Flow nozzle
The flow nozzle is used for high velocity flow measurement where erosion or cavitation could wear or damage an orifice plate.
Flow nozzles are available in three basic designs:
- ISA 1932 nozzle
- Long radius nozzle
- ASME throat tap nozzle
Each design is slightly different and is covered by ISO5167:2003, with the exception of the ASME throat tap nozzle. The ASME nozzle can also be supplied in a pipe section to meet the requirements of ASME Performance Test Code 6 (PTC-6) for steam turbine testing.
