Product Usage:
The rotary wing single flow dry cold (hot) water meter is used to measure the amount of hot water flowing through the tap water pipeline in a household or residential unit.
Usage conditions:
Temperature rating: T30 (cold water) T90 (hot water)
Water pressure level: MAP 10
Pressure loss level: △ P 63
Indication error limit:
From the low zone including the minimum flow rate (Q1) to excluding the boundary flow rate (Q2) ± 5%
From high zone cold water including boundary flow (Q2) to high zone cold water including overload flow (Q4) ± 2%, hot water ± 3%
Main features:
Dry type, magnetic transmission, and anti magnetic function; Single stream beam; Using high-quality materials with stable and reliable performance;
The counter adopts vacuum sealing, anti condensation atomization, and can maintain clear readings for a long time; It can be adjusted internally or externally;
Small size and light weight;
The case can be made of copper or plastic.
