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 need for power supply, long service life,
suitable for measuring high temperature, high pressure and corrosive media, but
the fluid is required to be stable 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.
