The ASME PTC-6 flow nozzle is a specialized differential pressure device designed to deliver the highest accuracy and repeatability required for steam turbine efficiency testing under the ASME PTC-6 Performance Test Code. Primary Flow Signal supplies PTC-6 nozzles as complete assemblies, including i

The ASME PTC 19.5 throat tap flow nozzle from PFS is engineered for high-accuracy differential pressure flow measurement in demanding, high-velocity services. It is widely used for steam turbine efficiency testing in accordance with ASME PTC 6, while also supporting broader power and process applica

Nozzle in compliance with ASME PTC 6 is a throttling device consisting of long radius nozzle that is together with flow straightener (downstream) built-in the meter tube. This layout represents a complete set with high degree of flow measurement accuracy. It is used for measurement of water flow in

Long Radius Throat-Tap Nozzles acc. ASME PTC-6 are available for performance testing of steam turbines in power generation plants. Extreme care must be taken to obtain the high order of accuracy necessary in primary water-flow measurement. There is always a need of a calibration. The SEIKO Throat-
