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.

What is the advantage of the compact orifice plate over a measuring flange?

The compact orifice plate integrates the primary flow element and the pressure tappings into a single assembly. In contrast to a measuring flange; fittings, tubing, valves, adapters and brackets can be dispensed with. It can be mounted between standa ...
