Coriolis flowmeter;

Mass flow meters serve to measure fluids and gases. The mass flow meter utilises the Coriolis force for flow measurement. The omega loop has proven itself particularly suitable for this process. The measuring tubes, which are bent to omega loops, are completed by two measuring bars and vertically secured torsion bars to create a harmonious oscillator. This carefully balanced and robust design has an extremely low power input. The frequency of the system essentially depends on the mass of the bars and the elasticity module of the torsion bars. Two electromagnetic coils set the system in motion. As soon as liquid or gas flows through the oscillating omega tubes, the resultant Coriolis force causes displacement of the tubes. The comparative relationship is established and the change in displacement is proportional to the mass flow. Application • i.a. custody transfer for mineral oils, bitumen and other viscous media
