Notices for Installation

Flush the pipework before installation to remove any dirt or other debris;
Install the valve and filter before the water meter;
Do not touch electrical components during installation and do not pull on wires to avoid damage;
When installing the water meter in a horizontal or inclined position, place the ultrasonic flow meter sensor horizontally in the pipework;
When installing it vertically, ensure that water flows from the bottom to the top.
When installing, note that the direction of the arrow on the pipe must be parallel to the direction of water flow;
Make sure to install the connection gasket correctly to prevent a misplaced gasket from blocking the water or affecting the accuracy of the water meter;
The water meter should not be installed in a place with strong mechanical vibration; Special precautions:
1. Switching valves and filters must be installed before the water meter, and it is recommended to install switching valves after the water meter for maintenance. To prevent backflow, a check valve should be installed before or after the water meter.

The pipe must be filled with water before this water meter can be used.
When installing the water meter, a length of DN*10 must be provided before the water meter. Alternatively, a length of DN*5 must be provided after the water meter.
The water meter will update its display every 15 seconds to read the water meter readings (including start and end values). The water meter should be tested for at least 5 seconds after the faucet is turned off.
During testing and use, ensure that the medium flow rate is within the flow range of the water meter.
If a malfunction (e.g., measurement error) occurs during use, immediately contact the Administration Department for repair.
The product has a unique safety seal that can only be removed by authorized personnel. If this is not removed, free after-sales service will not be provided.
