Product details
Product Usage
The rotary piston volumetric water meter is used to measure the amount of drinking cold water flowing through a water pipeline in a household or residential unit.
Usage conditions
Temperature level: T30
Water pressure level: MAP 10 / MAP 16
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 the high zone including boundary flow (Q2) to the high zone including overload flow (Q4) ± 2%
main features
Adopting the principle of rotary piston measurement, the measurement range is wide and the sensitivity is high. The installation position is not limited in any way and can be installed horizontally, vertically, or diagonally without affecting the measurement accuracy.
The digital wheel of the counter is sealed with special liquid, which can maintain clear readings for a long time.
The moving parts are made of high-quality wear-resistant materials, with stable and reliable performance.
The surface of the watch case is sprayed with plastic, which is beautiful and durable.
