Wide Range of Applications
The flow nozzle design is based on the Bernoulli equation and consists of a converging inlet section with a rounded profile and a cylindrical throat.
Thanks to its structurally rigid design, the flow nozzle provides greater dimensional stability than an orifice plate under high-temperature and high-flow conditions.
Flow nozzles are generally used to measure the flow of steam, non-viscous, abrasive, and high-velocity fluids.
These nozzles are also widely used in processes involving steam, air, water, gases, chemicals, and high-temperature applications.
A hardened internal surface option is available for use in abrasive service conditions.
High Accuracy
The design and manufacture of flow nozzles comply with the requirements of the ISO 5167 standard.
This provides an accuracy of ±1.0%.
With calibration, the accuracy can be improved to ±0.25%.
Flow nozzles compliant with the ASME PTC-6 standard are also available for power plant acceptance testing.
