Product details

  Product Usage

The rotary wing dry single flow water meter is used to measure the amount of cold (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
