Electromagnetic flowmeter, turbine flowmeter and vortex flowmeter

Electromagnetic flowmeters, turbine flowmeters and vortex flowmeters are commonly used flowmeters, they have their own characteristics and use environment, the following is their comparison description:

1. Electromagnetic flowmeter: no mechanical moving parts, stable measurement, accurate, simple maintenance, but can not measure non-conductive liquid

- Wide application range, large flow rate range

- Liquid containing solid impurities can be measured

- No influence of liquid flow rate, pressure, temperature, viscosity, density and conductivity changes

- Higher price

2. Turbine flowmeter: more moving parts, long time use may appear wear, high accuracy, wide range of application, but the cleanliness of the medium is required

- High measurement accuracy, suitable for high-precision measurement

- The flow rate range is limited, and the structure is complex

- The cleanliness of the measuring medium is required

- Affordable

3.Vortex flowmeter: no power supply, long service life, suitable for high temperature, high pressure and corrosive media measurement, but requires fluid stability, can not be used to measure pulsating flow

- Average measurement accuracy, but good stability

- Equipment structure is simple, easy to maintain

- Can be used for high temperature, high pressure and corrosive media measurement

- The flow sensor requires no power supply and can be used in explosive hazardous environments

- requires fluid status and cannot be used to measure pulsating flow

- The price is lower

The above are some basic comparisons, and the specific type of flowmeter used needs to be selected according to the specific application environment and needs.
