Coriolis mass flowmeters

This type of flow meter is based on the Coriolis effect (named after the researcher, Gaspard-Gustave Coriolis)

Mass flow

A Coriolis mass flow meter measures mass flow. This alone distinguishes this measuring technique from other flowmeters. Furthermore, each manufacturer has chosen a particular shape for the measuring tubes whereby it is not the case that there is only one best shape. Each shape has its advantages and limitations, but all instruments give a valid measurement signal for the density. For each application we will consider which option is preferable.

Coriolis flow measurement technique

Most Coriolis mass flowmeters have two parallel tubes that are attached to flanges and are vibrated by means of a bobbin located in the middle. The largest amplitude is located in the middle of the tubes. Tubes vibrate when no medium runs through, but no Coriolis force occurs. However, when mass flows through the measuring tubes, a reaction force does occur. The reaction force is directed at the inflow side opposite to the other side, which causes swabbing (out of phase) of the tubes. This phase shift is proportional to the mass flow. Each meter has a built-in temperature sensor that measures the temperature of the product.

Modern instruments are often equipped with DSP (digital Signal Processing). In this process, the real measurement signal is better isolated from the noise, which leads to an improved measured result.
