进口液体涡轮流量计产品用途 Product use进口液体涡轮流量计2.jpg

液体涡轮流量具有结构简单、轻巧、精度高、复现性好、反应灵敏,安装维护使用方便等特点,广泛用于测量封闭管道中与不锈钢1Cr18Ni9Ti、2Cr13及钢Al203、硬质合金不起腐蚀作用,且无纤维、颗粒等杂质,工作温度下运动粘度小于5×10-6m2/s 的液体,对于运动粘度大于5×10-6m²/s的液体,可对流量计进行实液标定后使用。若与具有特殊功能的显示仪表配套,还可以进行定量控制、超量报警等,是流量计量和节能的理想仪表

Liquid turbine flow has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and convenient installation, maintenance, and use. It is widely used for measuring closed pipelines, and is not corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13, steel Al203, and cemented carbide, and is free of impurities such as fibers and particles. Its kinematic viscosity at operating temperature is less than 5 × 10-6m2/s liquid, for kinematic viscosity greater than 5 × 10-6m ²/ S of liquid, which can be used after calibrating the flowmeter with real liquid. If matched with a display instrument with special functions, it can also perform quantitative control, excess alarm, etc. It is an ideal instrument for flow measurement and energy conservation
