Coriolis mass flowmeter is based on the Coriolis principle, so that the medium flows through the flow tube vibration, the sensor detects and analyzes the flow tube frequency, phase difference and amplitude changes, directly measure the current flow of the flow tube media quality, from the vibration frequency, calculate the density. Multiple process variables of the pipeline can be measured at the same time, such as: mass flow, volume flow, density, temperature.
Coriolis Flow meter VS Thermal Flow meter:
Coriolis flowmeters measure mass flow directly. Direct mass flow measurement reduces inaccuracies caused by fluid physical properties. Thermal flowmeters measure mass flow indirectly. There are fundamental differences between the two devices because of the way they are measured, and therefore the applications for which they are suitable are also different.
Thermal mass flowmeters use the heat capacity of a fluid to measure mass flow. The device is equipped with a heater and 1 or 2 temperature sensors for heating (1 sensor) the applied power or temperature difference between the 2 sensors is directly proportional to the fluid mass flow rate. Thermal mass flowmeters are mainly used for gases.
Because the Corrioli principle directly measures the mass flow rate, Corrioli flowmeters can be used for gases and liquids.
Applications:
Coriolis mass flowmeters can be used to measure the mass flow of changing or unknown gas or liquid mixtures or to measure supercritical gases. It not only directly measures the mass flow rate, but also has high accuracy and good repeatability. Coriolis flow meters are flexible, reliable and accurate flow meters.
