四、应用概况和选用考虑要点1.应用概况电磁流量计应用领域广泛.大口径仪表较多应用于给排水工程;中小口径常用于高要求或难测场所,如钢铁工业高炉风口冷却水控制和监漏,造纸工业测量纸浆液和黑液,化学工业的强腐蚀液,有色冶金工业的矿浆,选煤厂的煤浆,长距离管道煤的水力输送等场所的流量测量和控制;小口径、微小口径常用于医药工业、食品工业、生物化学等有卫生要求的场所. Fourth, the application of the overview and selection of considerations 1. Application Overview Electromagnetic flowmeter wide range of applications. Large diameter meter is more used in water supply and drainage projects; small and medium caliber commonly used in demanding or unpredictable places, such as steel blast furnace tuyere cooling water control and Leakage monitoring, pulp and paper industry in the measurement of black liquor, chemical industry, strong corrosive liquid, non-ferrous metallurgy industry pulp, coal preparation plant coal slurry, long-distance pipeline hydraulic transmission and other places of the flow measurement and control; small caliber, Small diameter commonly used in the pharmaceutical industry, food industry, biochemistry and other health requirements of the place.
