Application: This range of water meter is used to measure the total quantity of cold potable water whichconsumed in household or a resident unit, passing through the pipeline. Feature: Adopt volumetric rotary piston principle of measurement with conformity to ISO 4064 Class C. High sensitivity enables the accurate measurement even at a low flow rate of 4 L/H. NoLocation 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:≤50C Working pressure:≤1.6MPa Maximum permissible error: (1) in the lower zone from qmin inclusive up to but excluding qt is ±5%. (2) in the upper zone from qt inclusive up to and including qs is ±2%;Compliance With Standard: ISO 4064 Class C
