Coriolis Meteran overview ScienceDirect Topics

The most common one is the Coriolis meter and is based on the principles of motion mechanics. When the drilling fluid enters the meter it is split between two flow tubes as shown in Fig. 1.28. During operation a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency.

Reducing Flow vs. Reducing PressureWhich is it CTG

Mar 30 2012 · A reduction in orifice size results in decreased flow as only so much liquid can pass through the orifice. In all of the above cases the inlet pressure is constant and the outlet pressure is effectively zero (atmospheric) as there is nothing to restrict flow on the exit side of the orifice.

Flow measurementWikipedia

For example an orifice plate produces a pressure drop that is a function of the square of the volume rate of flow through the orifice. A vortex meter primary flow element produces a series of oscillations of pressure. Generally the physical property generated by the primary flow element is more convenient to measure than the flow itself.

Electromagnetic Flow Meters Design Considerations

The AD7172-2 provides the perfect combination of low input noise and high speed sampling for Electromagnetic flow applications. The typical noise of AD7172-2 with 2.5 V external reference can be as low as 0.47µV p-p. This means the final flow results can be refreshed at up to 50 SPS without the addition of extra amplification stages.
