Model LWG-Y turbine flowmeter is manufactured by our company with advanced technology from abroad, and is one of the most ideal flowmeters for measuring liquid. It has the characteristics of simple structure, high measurement accuracy, long service life, simple operation and easy maintenance. The product is widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields, high-precision measurement of water, tap water, diesel, gasoline and low viscosity crude oil volume flow.
Operating Principle
The turbine in the sensor rotates under the action of fluid, which changes the magnetic field of the signal detector. Therefore, the alternating voltage is induced in the coil of the signal detector, and the square wave signal is amplified, filtered and shaped by the amplifier. The frequency of the signal voltage is proportional to the speed of the impeller, that is, to the flow rate.
Features
LWG-Y turbine flowmeter has three series: G (high pressure), Z (medium pressure) and D (low pressure). Its operating pressure is up to 42Mpa.
The full carbide shielded cantilever beam bearing is used, which integrates the rotary bearing and the pressure bearing. The service life of the bearing is greatly improved, and it can work in a small amount of mud and dirt.
The sensor adopts all stainless steel structure and the turbine adopts 2Gr13. It has good corrosion resistance. Samarium drill permanent magnet alloy as a signal detector has strong output signal and good magnetic stability. It can work normally in the medium of 0 - 120 ℃.
Easy maintenance, flowmeter has self-rectifying structure, small and light, simple structure, can be assembled and disassembled in a short time, simple internal cleaning.
