The turbine flowmeter is a velocity flow measurement instrument based on the fluid kinetic energy driving the impeller to rotate. Its working principle is to convert the flow value by detecting the linear relationship between the impeller speed and the fluid flow rate.
1. Working principle
1. Fluid drive: When the fluid flows through the straight pipe, it drives the turbine blades to rotate, and the flow rate is proportional to the impeller speed.
2. Signal conversion: When the impeller rotates, it cuts the magnetic lines of force, and the magnetoelectric induction device (such as the Hall sensor) converts the mechanical rotation into an electrical pulse signal.
3. Flow calculation: The pulse frequency corresponds to the speed, and the instantaneous volume flow rate and the cumulative total are calculated in combination with the cross-sectional area of the pipe.
2. Technical features
- High precision: ±0.2%~±1% repeatability error, the preferred instrument for trade settlement.
- Wide range ratio: up to 1:20 (large diameter) or 1:10 (small diameter).
- Low maintenance: compact structure, high pressure resistant design (up to 6.3MPa), suitable for high temperature/low temperature environment.
- Signal output: The pulse frequency signal has strong anti-interference, supports digital transmission and computer integration.
- Limitations: Requires clean fluid (to prevent impeller jamming), sensitive to viscosity, and requires straight pipe section for installation.
3.Main categories
| Type | Applicable media | Typical scenarios | Features |
| Gas turbine flowmeter | Natural gas, compressed air, etc., gas pipeline network | Industrial gas metering, with pressure/temperature compensation | Rectifier shortens straight pipe section |
| Liquid turbine flowmeter | Water, petroleum, chemical solvents | Petrochemical, pharmaceutical (sanitary connectors) | Corrosion-resistant material (304/316 stainless steel) |
| Insertion turbine flowmeter | Large diameter liquid/gas | Municipal water supply, large pipeline monitoring | No flow interruption during installation, low pressure loss |
| Fuel-specific type | Diesel, aviation fuel | Energy metering, engine fuel monitoring | Explosion-proof design, high pressure resistance |
4. Application areas
- Energy trade: Natural gas trade settlement (one of the legal instruments in Europe and the United States).
- Industrial process: petrochemical process monitoring, clean fluid metering in the pharmaceutical industry.
- Public utilities: tap water flow monitoring, gas transmission and distribution network.
Tips: The selection needs to consider the cleanliness, viscosity and installation conditions of the medium. High viscosity fluids or impurity-containing media may cause measurement deviations or impeller wear.
