Installation, use and maintenance methods
1. Select the diameter of the water meter. The water meter of the appropriate diameter should be selected according to the diameter of the pipeline and the flow rate of the installation site.
2. The installation location should avoid exposure to sunlight, flooding, freezing and pollution, so as to facilitate disassembly and meter reading, and measures should be taken to prevent rain and frost in the rainy season and winter.
3. Before installation, the hemp wire, sand and other debris in the pipeline should be removed to avoid water meter failure.
4. During installation, valves and filters should be installed in front of the water meter to cut off the water source to disassemble the water meter and prevent debris from damaging the water meter.
