Wide variety of applications
The design of the flow nozzle is based on Bernoulli's equation and consists of a
convergent section with a rounded profile and a cylindrical throat. Due to its
rigidity the flow nozzle is dimensionally more stable at higher temperature and
flow rate than an orifice.
The flow nozzle is generally used for measuring the flow of steam as well as non
viscous, erosive and high-velocity media. It can be used in a wide variety of
applications that include steam, air, water, vapour, gas, chemical substances and
high temperatures. For applications with erosive media a hardened internal
surface is available.
High accuracy
The design and manufacture of the flow nozzles complies with the requirements
of ISO 5167. Thus an accuracy of ±1.0 % is ensured. By means of a calibration a
higher accuracy of down to ±0.25 % can be achieved.
For acceptance tests of power plants, flow nozzles to ASME PTC-6 are also
available.
