Product Usage
The highly sensitive anti drip wet water meter (models LXS-15E~20E) is used to measure the amount of drinking cold water flowing through the tap water pipeline in households or residential units.
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
Wet, multi beam, rotor type, low starting flow rate, easy to read.
Stable and reliable performance, long service life, beautiful appearance, strong universality of water meters, easy replacement and maintenance.
The material for the water meter case can be selected from copper, iron, stainless steel, engineering plastics, and aluminum alloy composite materials.
Sensitive, starting speed ≤ 2 L/H
Measurement accuracy meets ISO4064 B-level standard
