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≤ 45º C(Hot water meter≤ 90º C)
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%. )
