Primary flow elements

Primary flow elements for special requirements

Orifice plates, meter runs, flow and Venturi nozzles, Venturi tubes, pitot tubes and restriction orifices are part of our portfolio of primary flow elements. All our primary flow elements are designed in accordance with the principles and requirements of international standards (ISO 5167/ISO TR 15377, ASME MFC, ASME PTC6, BS 1042, DIN 19206, UNI 10023). We offer calibration certificates in accordance with the ASME PTC6, ISPESL and IBR standards. With our extensive product range we are in a position to cover almost all industrial applications. Customised solutions can be developed to meet your specific needs.
FAQ
FAQ

What are restriction orifices for and when are they used?

Restriction orifices are used to achieve a controlled or restricted flow. They prevent a too high loading of the primary flow element, and also prevent the possibility of cavitation. Restriction orifices can also be used for controlling the pressuris ...

How can the differential pressure be measured with a primary flow element?

In order to measure the differential pressure, a combination of primary flow element and differential pressure transmitter is needed.

What is cavitation?

Cavitation is the generation of vapour bubbles. Vapour bubbles implode after a short time and can generate high pressures with this.
