Description
The sanitary type turbine flowmeter LWGYN-L3 has the advantages of simple structure, light weight, high precision, good repeatability, quick response, convenient installation and maintenance, and is used in petroleum, chemical industry, metallurgy, water supply, paper making and other industries. The sensor can be used with display instrument to measure the liquid which is not corroded by stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and hard alloy, and has no fiber, particle and other impurity. If with a special function of the display instrument supporting, you can also carry out quantitative control, excessive reminder, etc. . The sensor is suitable for the medium whose viscosity is less than 510-6m2/s at working temperature. For the liquid whose viscosity is more than 510-6m2/s, the sensor should be calibrated with real liquid.
