Product Description
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: 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≤ 1mpa Maximum 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%. )
