4-20mA High Accuracy liqiud intelligent LCD electronic explosion-proof ss304/316 oil wastewater flowmeter turbine flow meter
The LWGY series turbine flowmeter is a new generation of turbine flowmeter that has absorbed the domestic and foreign flow meter cash technology and has been optimized and designed. It has the characteristics of simple structure, light weight, high precision, good reproducibility, responsiveness, easy installation and maintenance, and is widely used. In the measurement of closed pipes, it has no corrosion effect with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum AI2O3, cemented carbide, and has no impurities such as fibers and particles. The kinematic viscosity at operating temperature is less than 5×10-6m2/s. For kinematic viscosity greater than 5×10-6m2/s liquid can be used after the liquid calibration of the flowmeter. If it is matched with a display instrument with special functions, it can also perform quantitative control and over-alarm alarm, etc. It is an ideal instrument for flow measurement and energy saving.
