Features:
1. Volumetric measurement by rotary piston;
2. High measurement accuracy.
All technical indicators of the water meter comply with ISO4064 Class C or D standards, or R160, R200 standards;
3.The counter is apart from the water, the numbers are clear and easy to read;
4. Completely plastic shell, solid and robust design, long service guaranteed.;
5. Applicable to pipe networks with clear water;
6.The inlet (when installed vertical), outlet (when installed horizontal) of the water meter is assembled with a check valve to prevent the backflow of the water;
7.The water meter can be added with remote-reading pulse output function according to user requirements.
Application:
Measuring the volume of cold potable water passing through the pipeline.
Working Condition:
1.Water pressure: ≤1.6MPa (16bar);
2.Applicable to cold water, the water temperature ≤50℃;
Maximum Permissible Error
±5% at the Low-Zone ranging from min flow/Qmin (including Qmin) to transitional flow/Qt (excluding Qt).
±2% at the High-Zone ranging from transitional flow/Qt to max flow/QS (both Qt and Qs included), if for hot water meter, ±3% error acceptable.
