Turbine flow meter

Turbine flow meters are mechanical instruments for precise, reliable flow measurement. They are most accurate with clean, low-viscosity liquids and are used in applications ranging from industrial processes to water treatment plants.

Operation

  • The fluid turns the turbine blades as it passes through the rotor.
  • The rotational speed of the turbine is proportional to the flow rate.
  • Magnetic or optical sensors detect the rotation of the rotor, and the electronics convert the signals into a flow rate.

Advantages

  • High accuracy: down to ±0.5% error, especially in systems with steady flow.
  • Wide temperature and pressure range: models with steel bodies and precision bearings can also be used in harsh conditions.
  • Analogue & digital outputs: easy integration with SCADA and PLC systems.
  • Cost-effective: more economical than other high-tech flow meters.

Applications

  • Fuel flow control
  • Measurement of low-viscosity chemicals
  • Cooling water and glycol control
  • Dosing of pure water and solutions

Considerations

  • The fluid must be clean and free of particles; solids can wear the turbine.
  • Calibration is required; periodic recalibration is recommended to maintain accuracy over time.
  • Flow direction and correct installation matter; reversed installation causes measuring errors.
