Electromagnetic flowmeters, turbine flowmeters and vortex flowmeters are all commonly used flowmeters. They each have their own characteristics and usage environments. The following is their comparison:
1. Electromagnetic flowmeter: no mechanical moving parts, stable and accurate measurement, simple maintenance, but cannot measure non-conductive liquids
- Wide application range and large flow rate range
- Can measure liquids containing solid impurities
- No influence from changes in liquid flow rate, pressure, temperature, viscosity, density and conductivity
- Higher price
2. Turbine flowmeter: It has many moving parts and may wear out after long-term use. It has high accuracy and wide application range, but it has requirements for medium cleanliness.
- High measurement accuracy, suitable for high-precision measurement
- There are restrictions on the flow rate range and the structure is complex
- High requirements for cleanliness of measuring media
- Fair price
3. Vortex flowmeter: no power supply required, long service life, suitable for measuring high temperature, high pressure and corrosive media, but requires stable fluid and cannot be used to measure pulsating flow
- Measurement accuracy is average, but stability is good
- The equipment has a simple structure and is easy to maintain.
- Can be used for measuring high temperature, high pressure and corrosive media
- The flow sensor does not require a power supply and can be used in explosive environments
- It has requirements on the fluid state and cannot be used to measure pulsating flow.
- Lower price
The above are some basic comparisons. Which type of flow meter to use depends on the specific application environment and needs.
