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: liquid sealed;Dry type;
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 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%.)
