Clamp flowmeter

1、 Introduction to Clamp Flow Meter
CS-LWGY seriesClamp flowmeterIt is a new generation turbine flowmeter that has been optimized and designed based on domestic and foreign flow meter technology. 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 closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3, and hard alloys, and have no impurities such as fibers or particles. The liquid has a kinematic viscosity of less than 5 × 10-6m2/s at working temperature. For liquids with a kinematic viscosity greater than 5 × 10-6m2/s, the flowmeter can be calibrated for real liquid before use 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 saving. Sensors are precision flow measurement instruments that can be used to measure the flow and total amount of liquids when paired with corresponding flow accumulation instruments. Widely used in the fields of petroleum, chemical, metallurgy, scientific research and other metrology and control systems. Turbine flow sensors equipped with sanitary fittings can be applied in the pharmaceutical industry. The integrated turbine flowmeter has an explosion-proof design and can display the total flow rate, instantaneous flow rate, and flow saturation percentage. The battery adopts a long-lasting lithium battery, and the service life of a single function odometer battery can reach more than 5 years, while the service life of a multifunctional display meter battery can also reach more than 12 months. The integrated meter head can display a wide range of flow units, including cubic meters, gallons, liters, standard cubic meters, standard liters, etc. It can set fixed pressure and temperature parameters to compensate for gases. In situations where pressure and temperature parameters do not change significantly, this instrument can be used for fixed compensation accumulation. The technical performance of liquid turbine flow meters can be calibrated using real flow for hydraulic oil, engine oil, and small-diameter specifications with high viscosity.
