Wide variety of applicationsThe 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 accuracyThe 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.
Reduced pressure loss through a Venturi nozzleTo reduce the pressure loss, a Venturi nozzle can be offered. It combines the standard features of a flow nozzle with a divergent section.
The profile of the model FLC-FN-VN Venturi nozzle is axisymmetric and consists of a convergent inlet section with a rounded profile, a cylindrical throat section and also a diffuser. The inlet of the Venturi nozzle has the same geometry as model FLC-FN-FLN (flow nozzle to ISA 1932).
