Product Usage
The rotary wet remote transmission water meter is used to measure the amount of drinking cold water flowing through the tap water pipeline in households or residential units, and can transmit the water consumption signal to secondary instruments over long distances.
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 high zone cold water including boundary flow (Q2) to high zone cold water including overload flow (Q4) ± 2%, hot water ± 3%
main features
Multi flow rate, rotor type, high measurement accuracy, small starting flow rate, easy reading, and sends a signal every 10 or 100 liters of water flowing in.
Stable and reliable performance, long service life, beautiful appearance, strong universality of water meters, easy replacement and maintenance.
This series of watch cases can be made of copper, iron, stainless steel, engineering plastics, and aluminum alloy composite materials.
The series has strong universality and is easy to replace and repair; Accurate measurement and durability.

Installation requirements
Before installing the water meter, the pipeline must be flushed; The sending water meter must be installed horizontally, and the vertical water meter must be installed vertically. Make the reading face of the water meter face up, with the arrow direction aligned with the direction of the water flow; The water meter must be installed in a dry, easy to disassemble and repair location in the surrounding environment. It is recommended to install it in a dedicated water meter box. Valves must be installed before and after the water meter.
