Rheonik Coriolis Flow Meter

The continuing need for more accurate flow measurements in mass-related processes (chemical reactions, heat transfer, etc.) has resulted in the development of mass flowmeters. Various designs are available, but the one most commonly used for liquid flow applications is the Coriolis meter. Its operation is based on the natural phenomenon called the Coriolis force, hence the name.

A 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, wide range of mass flowrate based system can be configured by detecting the mass flowrate in high accuracy and sensitivity and converting it to analog or frequency output. In addition to general liquids, flowrate 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 flowrate.

Coriolis meters are true mass meters that measure the mass rate of flow directly as opposed to volumetric flow. Because mass does not change, the meter is linear without having to be adjusted for variations in liquid properties. It also eliminates the need to compensate for changing temperature and pressure conditions. The meter is especially useful for measuring liquids whose viscosity varies with velocity at given temperatures and pressures.

Coriolis meters are also available in various designs. A popular unit consists of a U-shaped flow tube enclosed in a sensor housing connected to an electronics unit. The sensing unit can be installed directly into any process. The electronics unit can be located up to 500 feet from the sensor.
