High Sensitive ，Anti-drippingWater Meter

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:
1.Type: wet
2.Low start flow
3.Wide measuring rang, 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 maximum flow-rate (qmax) exclusive: ±2%(hot water meter±3%.)
