Electromagnetic Interference

At present, most electronic devices have taken electromagnetic protection measures, but the old equipment may not take appropriate protection measures, the radio frequency energy radiation may fail. When using the GPRS low power remote meter, the equipment in the near range should be checked if the electromagnetic protection is done.

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
