LWGY Series Liquid Turbine Flow Meter
Product Description
Liquid turbine flow meter is a new generation of turbine flow meter with the characteristics of simple s truc ture, light weight, high prec i s ion, good repea t abi l it y, sens iti ve response, convenient installation and maintenance, etc. In the closed pipeline, it has no corrosion effect with stainless steel 1Cc18Ni8Ti, 2Cr13 and corundum AI3O3 cemented carbide, and has no fibers, particles and other impurities. The kinematic viscosity at working temperature is less than 5×10-6m2/s. For liquids with kinematic viscosity greater than 5×10 The liquid of – 6m2/s can be used after real-liquid calibration of the flow meter. If it is matched with a display instrument with spec ial func tions , it can al so carry out quantitative control, and an excess alarm light is an ideal instrument for flow meter and energy saving.
Features
