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

Leves complement ideally to flow measurements, since each flow is coming from a container or is pumped into a tank or container. For this the level information is extremely important because through these pumps and valves can be controlled, so that the flow can be measured with high reliability. In case of emptying tanks, the pump power can be reduced, so that the risk of air in the pipes is reduced. This in turn would affect the measurement. During tank filling can by throttling the power of the pump a overfilling be avoided so that the full capacity of a tank can be exploited. The level measurement in combination with the flow measurement complement each other ideally, if the measured information are processed together and evaluated. The plant availability is held high, because in case of failure or maintenance of a measurement, the other still works. Energy optimized, high-frequency electromagnetic impulses, generated by the electronics, are propagated along the probe (single rod..

The operation of the Oriflow Compact Orifice is based on the measurement of differential pressure, which is created across that section of a pipe where its cross section is reduced. This is then taken as a measure for the flow.
