Applications:

Suitable for measuring the flow rate of pure liquids such as tap water, alcoholic beverages, soft drinks, and oils, as well as gases such as steam, compressed air, and nitrogen; also suitable for flow measurement, volumetric metering, and flow display in industrial automation systems.

Suitable for measuring the flow rate of sewage, wastewater, and acid/alkali/salt liquids; also suitable for measuring the flow rate of high-temperature, high-viscosity liquids such as adhesives; suitable for measuring the flow rate of small liquids.

The turbine flow sensor is based on the torque balance principle and belongs to the velocity-type flow meter category. The sensor features a simple and lightweight structure, high accuracy, good repeatability, sensitive response, and convenient installation, maintenance, and use. It is widely used in industries such as petroleum, chemical, metallurgy, water supply, and papermaking. It is suitable for measuring liquids in closed pipelines that do not corrode stainless steel (1Cr18Ni9Ti), 2Cr13, corundum (A1203), or hard alloys, and are free of impurities such as fibers and particles.

When paired with a display instrument with special functions, it can also perform quantitative control and over-limit alarms. An explosion-proof type (ExdIICT6Gb) is available for use in environments with explosive hazards. The sensor is suitable for media with a viscosity less than 5 x 10⁻⁶ m²/s at the operating temperature. For liquids with a viscosity greater than 5 x 10⁻⁶ m²/s, actual liquid calibration is required before use.

Working Principle: When the liquid being measured flows through the sensor, the impeller rotates under the influence of the fluid, and its rotational speed is proportional to the average flow velocity in the pipe. The rotational period of the impeller changes the magnetic reluctance value of the magnetic circuit, causing the magnetic flux in the detection coil to change periodically, generating an induced electromotive force with the same frequency as the impeller rotation frequency. This induced electromotive force is amplified, converted, and processed.
