Application of Common Flowmeters

Common industrial flowmeters were introduced and classified, such as differential pressure flowmeter, vortex flowmeter, turbine flowmeter, float flow meter, digital target type flowmeter, electromagnetic flowmeter, ultrasonic flowmeter. Characteristics and application scope of different, flowmeters were discussed. The differential pressure type flow meter has advantages of, simple and stable structure, long life, but has disadvantages of low measuring progress, environmental restriction. Vortex, turbine flowmeter can measure some varieties of media without the parameter influence, but the turbine flowmeter is easily blocked. Float flow meter has the advantages of low pressure loss and stable, can measure low flow medium, but it is not suitable for the measurement of fluid with particle Digital fluid flowmeter has high temperature resistance characteristic, but has high requirement for medium. Electromagnetic flow meter and target type flowmeter are complementary. Ultrasonic flowmeter can measure various media, but the technology remains to be improved.
