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%. )
