Product Usage
The E-type horizontal spiral wing wet cold (hot) water meter is used in industrial and mining enterprises to measure the total amount of cold (hot) water flowing through the tap water pipeline.
Usage conditions
Temperature rating: T30 (cold water) T90 (hot water)
Water pressure level: MAP 10 / MAP 16
Pressure loss level: △ P 10
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
Using high-quality materials with stable and reliable performance; Low pressure loss. Series and strong universality.
