Coriolis flow meters are the perfect tool for measuring both liquids and gases. The flow measurement is independent of changes in process conditions/parameters such as temperature, density, pressure, viscosity, conductivity and flow profile. Due to this versatility and very large turndown the meter is easy to install and use in many various applications.
How does it work?
In a Coriolis flow meter, the mass is flowing through a tube and this tube is vibrating up and down. As flow enters the inlet side of the vibrating tube, the fluid encounters the motion of the tube for the first time. The fluid flowing in the tube is not in up or down motion relative to the tube when it enters it. Following the rule that states that things at rest tend to stay at rest unless acted on by an outside force, the fluid in the tube resists the motion of the tube. As far as the fluid is concerned, it does not want to move up and down. This resistance to the up and down motion slows the vibration of the inlet part of the tube, and this opposition is how, in part, a Coriolis meter measures mass.
