Tiivikvoolumõõdikud

Tiivikvoolumõõdikud, also known as turbine flow meters, are devices used to measure the flow rate of fluids in a pipe. They operate on a simple principle: a rotor with blades, or a turbine, is placed in the path of the fluid. As the fluid flows, it strikes the turbine blades, causing the rotor to spin. The speed at which the rotor spins is directly proportional to the velocity of the fluid.

The rotational speed of the turbine is typically measured by a sensor, which can be magnetic or optical. A magnetic sensor detects the passage of magnets embedded in the rotor or the rotation of a ferromagnetic rotor itself. An optical sensor uses a light beam and a receiver to count the interruptions caused by the rotating blades. This rotational speed is then converted into a flow rate using a calibration factor.

Tiivikvoolumõõdikud are known for their accuracy and reliability, especially for clean liquids and gases. They are commonly used in various industrial applications, including the measurement of water, oil, gas, and steam. Their advantages include a relatively low pressure drop, a wide range of flow rates they can measure, and their ability to operate at high temperatures and pressures. However, they can be sensitive to impurities in the fluid, which can cause wear on the turbine blades or lead to inaccurate readings. Regular maintenance and calibration are often recommended to ensure optimal performance.
