E Vane Wheel Water Meter (LXSGR-15E~50E)

DEFINITION:Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow.WORKING PRINCIPLES:Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded.CHARACTERS:For hot water.Outside adjust copper body,painted available as demanded.Counter:vacuum sealed, frost proven, keeping clear reading for long.Magnetic transmission free from disturbance.WORKING CONDITION:Water temperature≤45ºC(Hot water meter≤90ºC)Water pressure≤1MpaMAXIMUM PERMISSIBLE ERROR:From the minimum flow-rate (qmin) inclusive to the lower zone of the transitionalflow-rate (qt) exclusive: ±5% .From the transitional flow-rate (qt) inclusive to the higher zone of the maximum flow-rate (qmax) exclusive: ±2%(hot water meter±3%.)
