Volumetric Rotary Piston Water Meter
APPLICATION
This range of water meter is used to measure the total quantity of cold potable water which consumed in household or a resident unit, passing through the pipeline.
FEATURES
Adopt volumetric rotary piston principle of measurement with conformity to ISO 4064 class C, D (R160-R200) High sensitivity enables the accurate measurement even at a low flow rate of 4 1/h No location limitation for installation. Accuracy is not to be affected wherever installed at a horizontal, vertical or inclined pipeline Register is sealed with a special liquid to keep a clear reading in long term service Mechanical parts use of high-quality material to ensure a stable characteristic
WORKING CONDITION
Water temperature: ≤ +50º C
Water pressure:≤1.6 MPa(16 bar)
COMPLIANCE WITH STANDARD
ISO 4064 Class C, D (R160 - R200)
INDICATING ERROR
At low zone is ± 5% from minimum flow rate(Q1) totransitional flow rate(Q2) exclusive boundary
At high zone is ± 2% from transitional flow rate(Q2) to overload flow rate(Q4)
