Product Details
1、 Product Overview of Small Diameter Turbine Flowmeters:
The LWGY small caliber turbine flowmeter is a new generation of turbine flowmeter that has been optimized and designed based on advanced technology of flow meters at home and abroad. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used to measure liquids in sealed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and hard alloys, and have no impurities such as fibers or particles. The liquid with a kinematic viscosity of less than 5 × 10-6m2/s at working temperature can be used after real liquid calibration for liquids with a kinematic viscosity greater than 5 × 10-6m2/s. If paired with display instruments with special functions, it can also perform quantitative control, over limit alarm, etc., making it an ideal instrument for flow measurement and energy conservation.
