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: The counter type: Horizontal. Sealed by special liquid keeping surface clear for long. Low start flow. Fit for low quality water. Outside adjustable copper body. Painted available as demanded. 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%. )
