Working Principle

The turbine flow meter operates on a simple and reliable concept of converting fluid flow energy into rotational motion. The core mechanical assembly consists of a precision turbine rotor, designed with an aerodynamic shape and made from magnetic material to ensure efficient energy conversion.

As the liquid flows through the pipeline, it strikes the turbine blades, causing the rotor to spin. The rotational speed of the turbine rotor is directly proportional to the velocity of the fluid, enabling accurate flow rate measurement.

The rotor shaft is supported by tungsten carbide bearings, which provide high durability, reduced friction, and long operational life, even under continuous industrial use.

A magnetic pickup sensor, mounted externally without penetrating the meter body, detects the rotation of the turbine. This sensor consists of a magnet and coil arrangement that senses the change in the magnetic field as the rotor blades pass by.

Each rotation generates a pulse signal, producing a frequency output proportional to the flow rate. This signal is then processed by the electronics to calculate and display:

  • Instantaneous flow rate
  • Totalized flow volume

The output can be easily converted into standard engineering units such as m³/hr, liters, kilograms, tons, and cubic feet, making it suitable for industrial flow measurement applications, including oil & gas, chemical processing, and water systems.
