Measurement Principle Of A Gas Coriolis Flowmeter

A gas Coriolis flowmeter uses thermal measurement to measure flow rate by measuring the molecular mass carried away by dissociated molecules. Because it uses thermal measurement, the measurement results are not affected by changes in gas temperature or pressure. Gas Coriolis flowmeters are highly accurate, fast, reliable, efficient, stable, and flexible flow measurement instruments. They are expected to be widely used in fields such as petroleum processing and chemical engineering, and are believed to have great potential in promoting flow measurement. Gas Coriolis flowmeters cannot control flow rate; they can only detect the mass flow of liquids or gases and output flow values via analog voltage, current, or serial communication. However, a mass flow controller (MFC) is an instrument that can both detect and control flow. In addition to the measurement component, a MFC also incorporates a solenoid control valve or piezoelectric valve, forming a closed-loop system for controlling the mass flow rate of the fluid. The setpoint for a MFC can be provided by analog voltage, analog current, or a computer or PLC.
