Coriolis mass flowmeters measure the mass flow of liquids, such as water, acids, caustic, chemicals, and gases/vapors.
Because mass flow is measured, the measurement is not affected by fluid density changes

Coriolis flow meters artificially introduce a Coriolis acceleration into the flowing stream. As the fluid is "deflected", the forces generated cause an extremely slight distortion or 'twisting action' of the measuring tube that is directly proportional to the mass flow rate. This distortion is picked up by special sensors and converted to an output signal.Coriolis mass flow meters can provide flow (mass or volume), density, and temperature measurements of liquids and gases all within a single meter. Since the measurement principle is independent of the physical fluid properties, these meters typically have a very high accuracy. The lack of straight pipe requirements and moving parts makes them a very attractive alternative to other flow meters.Selecting a Flow MeterThe basis of good flow meter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation.What is the fluid being measured by the flow meter(s) (air, water, etc…)?Do you require rate measurement and/or totalization from the flow meter?If the liquid is not water, what viscosity is the liquid?Is the fluid clean?Do you require a local display on the flow meter or do you need an electronic signal output?What is the minimum and maximum flow rate for the flow meter?What is the minimum and maximum process pressure?What is the minimum and maximum process temperature?Is the fluid chemically compatible with the flow meter wetted parts?If this is a process application, what is the size of the pipe?
