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: Types: Wet, dry, vertical, liquid sealed. Wide measuring range, high accuracy. Stable measuring capacity Long working life Low pressure loss All 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≤ 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%. )
