What is a Coriolis mass flow meter?

 What is coriolis flow meter?

Coriolis mass flow meter design can vary, but in general, it consists of several basic elements:

Tube (tubes);

· Sensors;

· Oscillation drive;

· Transducer

Tube is a zone where basic measurements take place. It is always U-shaped. Sometimes two of these tubes can be used for better flow sensitivity. In this case, a flow splitter is also presented. It directs half of the main flow to each tube.

Sensors are placed at the input and output of the tube. They record changes in oscillations at the system inlet and outlet.

Oscillation drive makes a tube vibrating with a constant frequency. The most popular method is usage of pair coils and magnets. In that case, the oscillation is made by magnetic fields. However, there is no need to equate them with electromagnetic flow meters. It is just an auxiliary process. There are also models with mechanical actuators, but they are less common.

Transducer collects signals after measuring and converts them into digital or analogue data. After that, the results can be shown on display or send further to control systems. It is always possible to install additional counters to accumulate and structure results autonomously.
