Coriolis Mass Flow Meter Principle & Overview

The structure of Coriolis Mass Flow Meters was consisted of a pair of bended tubes. The principle is to detect Coriolis force which is forced on a pair of tubes from inner mass flow by fluid.

A new force-Coriolis force would be appearing while two conditions are met:

a. Vibrating with normal frequency in a pair of bended tubes,

b. Fluid flowing in tubes. This force was produced upon synthesis from vibrating force and flowing force by fluid in tubes. And tubes would be wresting symmetric the center line because the force forced. Two displacement sensors on sides of tubes detect the force and output electric signals.

The signals regulated and mass flow directly produced.

Coriolis mass Flow meter can take direct measurement of mass flow with high accuracy. It can measure gas,liquid and steam, it can even measure liquid containing small amount of gas ,such as it is used as Refrigerant flow meter.

Various fluids can be measured by Coriolis mass flow sensors, it can be used as asphalt mass flow meter, molasses flow meterssyrup flow meters, glucose flow meter, slurry flow meter,it is a kind high viscosity flow meter.

Insensitive to fluid flow rate distribution, so have no requirement for the straight pipe requirements

Mass Flow measurement is not affected by media characteristics

Multiple parameters such as density measurement, temperature, viscosity, and concentration of solute in solution can be measured by Coriolis meter.
