Compact orifice

The compact orifice Oriflow is used for flow measurements of conductive and non-conductive fluids, gases and vapours in all industrial branches.

Our strategic business unit (SBU) METRA Energie-Messtechnik has taken over this area. Our team will be happy to answer any questions you may have.

Application:

Applications include flow measurements (volume / Mass) for balancing (compressed air systems, heat carries, vapours, chemical products, for examples), process control and high throughput applications, redundant solutions for safety applications
