Principle, structure

Turbine flowmeter is a type of velocity flowmeter. As shown in the figure below, a turbine is placed at the center of the pipeline, supported by bearings at both ends. When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque on the turbine, causing it to overcome friction torque and fluid resistance torque and rotate. Within a certain flow range, the viscosity of the fluid medium and the rotational angular velocity of the turbine are proportional to the fluid flow velocity. Therefore, the fluid flow velocity can be obtained by the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated.

The speed of the turbine is detected by a sensing coil installed outside the casing. When the turbine blades cut the magnetic field lines generated by the permanent magnet inside the casing, it will cause changes in the magnetic flux in the sensing coil. The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier, amplifies and shapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flow integration circuit to obtain and display the accumulated flow value; At the same time, the pulse signal is also sent to the frequency current conversion circuit, which converts the pulse signal into an analog current quantity and indicates the instantaneous flow rate value.
