FAQ

Where can the discharge coefficients Cv be obtained?

The discharge coefficients Cv can be obtained from the standard (ISO 5167) for nozzles, Venturi tubes and orifice plates that are manufactured to the specified tolerances of the standard.

Which are the recommended upstream/downstream straight lengths for orifice plates and Venturi tubes?

The upstream and downstream straight lengths depend on many factors, such as the piping system and the beta ratio, for which reason no blanket statement can be made on this. If you have any questions on your specific application, you are welcome to contact us.
