Installation: Horizontal Caliber：DN15/20/25/32 Usage It is used to measure the water flow in the pipeline and has the function of prepayment at the same time. Techniques There is no mechanical part of electronic prepaid water meter. It can collect signals directly to the main board by the impeller. The acquisition frequency is higher, it is not easy to lose the number, and the measuring precision is higher relative to the mechanical meter. It can compensate the error of the mechanical part through the electronic part, and can show the flow velocity.

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. 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
