The SHG-L turbine flowmeter is based on the principle of torque balance and belongs to the velocity flow instrument. Flow meter sensors are ideal instruments for flow measurement due to their simple structure, lightweight, high accuracy, good repeatability, sensitive response, and easy installation, maintenance, and use. The product is sturdy, simple, and has a long service life. It is used for measuring and process control of liquid and gas media in industries such as petroleum, chemical, metallurgy, power, medicine, food, and papermaking.

Working principle: When the measured liquid flows through the sensor Under the action of fluid, the impeller rotates under force Its rotational speed is directly proportional to the average flow velocity of the pipeline The rotation of the impeller periodically changes the magnetic resistance value of the magnetic circuit Detecting the magnetic flux in the coil It undergoes periodic changes and produces a frequency that is the same as the blade rotation frequency Induced electromotive force, after amplification, is converted and processed.
