5,Installation Notes:
(1). The diameter of the water meter should be selected according to the diameter of the pipeline at the installation site and the flow rate should be less than or equal to the usual flow rate;
(2). The installation location should be selected where it is easy to disassemble and read the power data of the water meter;
(3). During installation, sand, gravel, tape, iron wire and other sundries should be prevented from entering the water meter pipeline, which may cause water meter measurement failure;
(4). When installing, the direction of water flow should be consistent with the direction of the water meter arrow;
(5). The water meter is not suitable for measuring hot water, please do not install it in hot water places such as solar energy and bathing;
(6). After installation, please switch to the signal display interface and read the signal value. The signal value should be more than one grid.

6,Window Operation 
The water meter is usually in a low-power off-screen state, and it can be woken up when the magnet is placed in the lower left corner of the screen (where the CPA logo is located). The magnet moves across the lower left corner of the screen to realize switching and cycling of the display window.
