Single Jet Rotary Vane Wheel Dry-Dial Magnet-Drive Cold Water Meter

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:Types: Wet, dry, vertical, liquid sealed.Wide measuring range, high accuracy.Stable measuring capacityLong working lifeLow pressure lossAll technical figures are conformed with GB/T778. 1~3-1996 which is equivalent to ISO4064 Standard Class B.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%. )
