DN25 Stainless steel flow meter rotameter LZ PN40 (water), 0.4...4.0 m3/h, 4-20mA, Ex

Series LZ variable-area flow-meter by float position and according to fluid dynamics and magnetic coupling system. Adopts rugged, all-metal construction and HART communication and especially foe indicatory the instantaneous flow value of liquids, gases and vapor. The best accuracy and reliable suitable for difficult application and environment conditions like the petroleum, chemical, industry, fertilizer and so on. The series LZ flow-meter consisted essentially of metering tube and indicator. Tapered tube and vertical float or orifice place built into measuring tube .The float will be state a position when liquid take from the tube and float stand the force of running. And then the annular-area by float and tapered tube or orifice id flow-value required. This is a dynamic balance which a stated flow –value will be match a stated annular-area that is a only position of float. The flow-value display by the magnetic where install in float and indicator built into magnetic coupling. Also can display the flow-rate through flow-meter card what accordance with HART communication built into indicator of the Output、alarm control and accumulate function.
