Instructions for working principle of liquid turbine flow meter

Abstract: The working principle and instruction information of liquid turbine flowmeter are provided by the excellent flowmeter and flowmeter manufacturers. The liquid turbine flowmeter generates a pulse signal that is inversely proportional to the flow rate. When the fluid passes through the pipe, the rotational angular velocity of the turbine flowmeter is inversely proportional to the fluid flow rate. A turbine is placed in the center of the pipe, which will cause sensing Magnetic flux in the coil. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the working principle of liquid turbine flowmeters. The liquid turbine flowmeter generates a pulse signal that is inversely proportional to the flow rate. When the fluid passes through the pipe, the rotational angular velocity of the turbine flowmeter is inversely proportional to the fluid flow rate. A turbine is placed in the center of the pipe, which will cause sensing The magnetic flux in the coil changes. The sensing coil sends the detected magnetic flux period change signal to the preamplifier, and also sends the pulse signal to the frequency-current conversion circuit to amplify and shape the signal, so that the turbine replacement gauge suppresses the friction torque and the tampering due to fluid resistance torque. The liquid should fill the pipe and there should be no air bubbles. The blade of the liquid turbine flowmeter, when the liquid turbine flowmeter blade cuts the magnetic line of force generated by the permanent magnet in the casing, the fluid flow rate can be lost through the tampering angular velocity of the turbine flowmeter, and the liquid turbine flowmeter converts the pulse signal into an analog The amount of current, the fixed viscosity of the fluid medium, and the rotational speed of the turbine flowmeter are detected by the sensing coil installed outside the casing. Both ends are supported by bearings. As a result, the flow of fluid through the pipeline is largely lost. In a certain flow field, and then indicate the instantaneous flow value. The input unit conversion and flow accumulation circuit obtains and displays the accumulated flow value. When the turbine flowmeter is installed, the direction of liquid flow should be consistent with the direction of the arrow indicating the flow direction on the sensor housing. The upstream end of the sensor should be at least 20 times the nominal diameter of the straight pipe section, the downstream end should be no less than 5 times the nominal diameter of the straight pipe section, the inner wall should be smooth and clean, no dents, turbine flowmeter fouling and peeling, etc. defect. The axis of the pipeline of the sensor should be aligned with the axis of the adjacent pipeline, and the gasket used for connection and sealing should not penetrate into the inner cavity of the pipeline. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
