When a fluid or liquid flows in a rotating tube, it will produce a force on the wall of the tube. It was discovered by Coriolis in 1832 when he studied the engine. In 1977, according to this principle, the founder of micro motion developed the world's first practical mass flow meter. Now in China we can also supply high quality mass flow meter to meet kinds of requirements. The mass flow meter is based on Coriolis force. There are two parallel flow tubes in the sensor. The drive coil is installed in the middle and the detection coil is installed at both ends. When the excitation voltage provided by the transmitter is added to the drive coil, the vibrating tube vibrates in a reciprocating cycle. When the fluid medium of industrial process flows through the vibrating tube of the sensor, the Coriolis force effect will be produced on the vibrating tube, which makes the two vibrating tubes twist The detection coils installed at both ends of the vibrating tube will generate two groups of signals with different phases, and the phase difference of the two signals is proportional to the mass flow of the fluid flowing through the sensor. The mass flow through the vibrating tube is calculated by computer.
