Supply LWGY turbine flowmeter LWGY-10 turbine flowmeter direct sales

Description :

　　This product has the characteristics of simple structure, high measurement accuracy, long service life, easy operation, and easy maintenance. Widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields.

　　1、 Principle

　　When the measured liquid passes through the sensor, the impeller inside the sensor rotates with the help of the kinetic energy of the liquid. At this time, the impeller blades cause periodic changes in the magnetic resistance (optical path cutting) of the detection device, resulting in the induction of electrical pulse signals proportional to the frequency and flow rate at both ends of the detection coil, which are amplified by an amplifier and transmitted remotely for output.

　　2、 Technical parameters

　　Execution standard: Turbine flow sensor (JB/T9246-1999)

　　Instrument diameter (mm) and connection method: 4, 6, 10, 15, 20, 25, 32, 40, 50, 65, 80 adopt threaded connection
