I. Introduction to Xiamen Jingchuan Co., Ltd. LRF Liquid Turbine Flow Meter

· The Xiamen Jingchuan Co., Ltd. LRF series liquid turbine flow meter is a new generation turbine flow meter that incorporates advanced technology from domestic and international flow instruments through optimized design. It features a simple and lightweight structure, high accuracy, excellent reproducibility, sensitive response, and convenient installation, maintenance, and use. It is widely used to measure liquids in closed pipelines that are non-corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and hard alloys, and free of fibers, particles, and other impurities, with a kinematic viscosity of less than 5×10?? m2/s at operating temperature. For liquids with a kinematic viscosity greater than 5×10?? m2/s, the flow meter can be used after calibration with the actual liquid. When paired with display instruments with special functions, it can also perform quantitative control and over-limit alarm functions, making it an ideal instrument for flow measurement and energy conservation.
