turbiinivoolumõõtja

A turbiinivoolumõõtja, or turbine flow meter in English, is a type of flow meter that measures the flow rate of a fluid (liquid or gas) by using a rotor that spins when the fluid passes through it. The rotor is typically a propeller-like device with blades that are set in motion by the kinetic energy of the flowing fluid. The speed of the rotor's rotation is directly proportional to the velocity of the fluid.

The rotation of the turbine is detected by a sensor, which can be magnetic, optical, or inductive. This sensor counts the number of revolutions or measures the frequency of the blade passages. This count or frequency is then converted into a flow rate using a calibration factor specific to the turbine and the fluid being measured. Turbine flow meters are known for their accuracy and reliability, especially in applications involving clean liquids and gases.

These flow meters are commonly used in various industrial sectors, including oil and gas, chemical processing, water treatment, and power generation. They are suitable for a wide range of flow rates and fluid temperatures and pressures. However, they are generally not recommended for fluids with high viscosity, significant solid content, or those that can cause erosion of the turbine blades, as these can affect the accuracy and lifespan of the device. Regular maintenance and calibration are important for ensuring the continued accuracy of a turbiinivoolumõõtja.
