KROHNE WEDGE FLOWMETER

The wedge flowmeter is designed for difficult applications where other flow technologies fail or have a very limited-service life. It can cope with high viscosities, abrasive solids-containing fluids or liquids with a tendency to scaling or agglomeration. The materials can pass the wedge restriction where other flow devices lead to material build-up in a kind of “damming” effect. Due to these advantages the wedge flowmeter has been established as a standard device in particularly difficult applications with harsh process conditions such as refineries where solid coke can pass the flowmeter along with the hot feed flow or in oil production and mining where solids are not yet separated from the stream.

KROHNE offers the complete wedge flowmeter with the wedge element, DP transmitter(s) including diaphragm-seals, accessories, engineering, testing and documentation from a single source. The pressure tapping is typically designed as flange connection for use with diaphragm seals and can be executed redundantly if required.

The sophisticated OPTIBAR DP 7060 and OPTIBAR DP 3050 DP transmitters are the perfect companion for this DP flowmeter solution. They are 3D linearised and ensure advanced performance even at high static pressures. The OPTIBAR DP series has an outstanding long-term stability and a low total cost of ownership with a reduced need for field calibrations.
