2. What is the difference between a turbine flowmeter and a turbine flow sensor? The turbine flowmeter consists of a turbine, bearings, preamplifier, and display instrument. The principle of a turbine flowmeter is to place a turbine in the center of a pipeline, supported by bearings at both ends. When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque for the turbine, which overcomes the friction torque and fluid resistance torque to produce rotation. Within a certain flow range, for a certain viscosity of the fluid medium, the rotational angular velocity of the turbine is proportional to the fluid flow velocity. Therefore, the fluid flow velocity can be obtained from the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated. The rotational 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 magnetic steel inside the casing, it will cause changes in the magnetic flux in the sensing coil. The sensing coil will send the detected magnetic flux periodic change disturbance signal to the front end. Amplifier, amplifying signals Shaping generates a pulse signal proportional to the flow rate, which is sent to the unit conversion and flow accumulation 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 and indicates the instantaneous flow rate value. The measured fluid impacts the turbine blades, causing the turbine to rotate. The speed of the turbine changes with the change of flow rate, that is, when the flow rate is high, the speed of the turbine is also high. Then, the speed of the turbine is converted into electrical pulses of the corresponding frequency by the magneto electric conversion device, amplified by the preamplifier, and sent to the display instrument for counting and display. The instantaneous flow rate and cumulative flow rate can be calculated based on the number of pulses and cumulative pulses per unit time. The working principle of a turbine transmitter is that when the fluid flows along the axis of the pipeline and impacts the turbine blades, a force proportional to the product of the flow rate qv, flow velocity V, and fluid density ρ acts on the blades, driving the turbine to rotate. While the turbine rotates, the blades periodically cut the magnetic field lines generated by the electromagne
