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.

1.Types: wet;

2.Low start flow;

3.Wide measuring range, high accuracy;

4.Stable measuring capacity;

5.Long working life;

6.Low pressure loss;

7.All technical figures are conformed with GB/T778.1~3-1996 which is

equivalent to ISO4064 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
transitionalflow-rate (qt) exclusive: ±5%
From the transitional flow-rate (qt) inclusive to the higher zone of the
maximumflow-rate (qmax) exclusive: ±2%(hot water meter±3%.)
