E Vane Wheel Water Meter (LXSG-15E1~50E1)

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:Counter: Vacuum sealed, frost proven, keeping clear reading for long.Magnetic transmission free from disturbance.Fine plastic meter body and cover. Outside adjustable.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%. )
