General
Coriolis flowmeter is a mass flowmeter to directly and continuously measure the “mass”, the only characteristic of fluid that is not affected by the change in temperature, pressure, viscosity, and density of it. Based on a unique principle utilizing Coriolis force, a wide range of mass flow rate-based systems can be configured by detecting the mass flow rate with high accuracy and sensitivity and converting it to analog or frequency output. In addition to general liquids, the flow rate of foods, chemicals, slurry, high-density gas, etc. can be measured. A major feature of the Coriolis flowmeter is a complex sensor that can measure temperature and density simultaneously with flow rate.
