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:
1.Types: wet.
2.Wide measuring range, high accuracy.
3.Stable measuring capacity.
4.Long working life.
5.Low pressure loss.
6.All technical figures are conformed with GB/T778.1~3-1996 which is equivalent to IS04064 Standard Class B.

WORKING CONDITION:
.Water temperature≤45℃(Hot water meter≤90℃)
.Water pressure≤1Mpa

MAXIMUM PERMISSIBLE ERROR:
.From the minimum flow-rate (qmin) inclusive to the lower zone of the transitional flow-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%.)
