CM Series Coriolis Mass Flow Meter directly measures the “Mass” of the medium with high accuracy based on the Coriolis Principle (Coriolis Force). The accuracy would not be affected by any factors like the temperature, pressure, density, viscosity, etc. The compensation calculation is not required. The Coriolis Mass Flow Meter consists of two parts; the sensor and the transmitter. The Coriolis Mass Flow Meter is designed and produced based on the national standard of explosion-proof standards. The Explosion-proof standard is Exd ib li Ct5 Gb.

Coriolis Mass Flow Meter could directly measure the “mass” of the liquid. The accuracy is the highest among all types of flow meter, saying, 0.1~0.2%. The range of application is very large, and it could be used for the medium that difficult to be measured, like, high temperature, high pressure, high viscosity, double phases, triple phases. The requirements for the installation are low, the straight pipe requirement in front of and behind the Coriolis Mass FLow Meters are low. They are more reliable, stable, and maintenance level is low.
