Product Features
1. Payment in advance, avoid debt.
2. LCD display function: the liquid crystal display screen displays the amount of water, the amount of the surplus, the accumulative amount, the state of the valve, the insufficiency of battery power, the indication of the wrong card.
3.When the remaining water amount is equal to the alarm amount, valve failure once. when the remaining water is used up, water valve failure again and the user shall buy the water again
4. Valve automatic maintenance function: regular on-off valve. Avoid disgrace of the valve.
5. Waterproof, moisture-proof and anti-attack.
6.The advantage is that it will be antifreeze in winter, and the impurities in the water meter will not cause dirty surface.
7.It needs to be used in the water quality preferably environment.

INSTALLATION.
1. The caliber of water meter shall be based on the size of the pipeline and the usual used water flow is no more than common flow of the water meter; and the installation location shall be avoided insulation , flooding, freezing and pollution, and convenient for installation, removing and reading data.
2. The sands and stones and other sundries in the pipeline, such as hemp thread shall be cleaned firstly in Case of water meter breakdown.
3. Please leave enough space for repairing, and installation according to water flow direction on the pipe.
4. Please do not apply too much force when connecting the water meter and pipe, to avoid damaging the meter body and leakage.
5.If the water meter is installed on the inlet of the boiler, shall install check valve on the outlet of water to prevent the return current of hot water and steam from damaging the water meter
