Measuring the volume of cold potable water passing through the pipeline.
Key structure is made up of rotary carried helical blades which goes around as the same direction of
water flow.
1. Types: clock hands and numerical rolls (E type);
2. For dry type cold water;
3. Simple structure;
4. Big flow capable, low head loss;
5. All technical figures are conformed with GB/T778.1~3-1996 which is to
equivalent to ISO4064 Standard.
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%.)
