Style:Separated Sturcture
/Vertical/Horizontally
Waterproof grade: IP65, IP68
Usage
Customers purchase water volume at vending points and upload water volume by swiping IC card on the induction area of water meter to activate valve, which will open automatically to supply water. During the period of water supply, the built-in microcomputer of water meter will automatically check and subtract the used water volume. Water meter has twice alarm function, when the purchased water volume reaches to alarm volume, water meter will close valve and stop water supply. Customer can continue to use water by swiping IC card on water meter. When the remain water volume is used up, water meter will stop water supply completely and the customer needs to charge his IC card again.

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 and should be installed horizontally.
4. Please do not apply too much force when Connecting the r 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.
NOTE
1. The water meter should be far away from high temperature, high humidity and high magnetic environment
2.Don’t hide with metal objects, according to the specifications.
3.It’s strictly forbidden to dismantle the table privately, otherwise the consequences will be conceited.
4.Our company will optimize products according to the situation every year, and we can't inform customers one by one. Our company has the right of final interpretation of product functions.
5.If you have any problem, please connect us, we will solve it as soon as possible. Thank you.
