Detailed description of the working principle of the turbine flowmeter

In order to measure the flow rate of the fluid, the accuracy of the measurement is increasing, in order to be able to measure different fluids. There are various types of flow meters on the market, but the accuracy and environment of the different flow meters are also different. They all follow different principles, but the ultimate goal is the same, both to make it easy to measure the flow of fluid.
For turbine flow meters, it has higher measurement accuracy, easy maintenance and so on. Widely used in the flow measurement of various fluids, but also because of its high-precision measurement capability, it is very popular among users.

How the turbine flow meter works
The turbine flow meter has a turbine that is installed in the fluid piping and supported at both ends by bearings. As the fluid passes through the turbine, the fluid impacts the turbine blades, causing the turbine blades to rotate. The meter of the turbine flow meter indirectly measures the flow rate through the angular velocity of the turbine blade. The method uses the angular velocity of the blade to be proportional to the fluid velocity.
The angular velocity is detected by the sensing coil mounted on the casing. When the turbine blade cuts the magnetic lines generated by the permanent magnet in the casing, the change in the magnetic flux of the sensing coil is changed. The sensing coil sends the detected magnetic flux cycle change signal to the amplifier of the measuring instrument, amplifies and shapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flowmeter integrated circuit to obtain and display the accumulation. The flow value is also sent to the frequency current conversion circuit to convert the pulse signal into an analog current amount, thereby indicating the instantaneous flow value.
The above is the working principle of the turbine flowmeter. The measurement method of the turbine flowmeter is to measure the flow velocity of the fluid through the angular velocity of the turbine blade, and then measure the flow rate of the fluid.
