1. The water meter should be installed horizontally without tilting, and the arrow on the meter case should be consistent with the flow direction of the pipeline.
2. The installation site should be protected from sun exposure and freezing, pollution and flooding, and easy to disassemble and read. Anti freezing measures should be taken in winter.
3. For the newly installed pipeline, the sundries in the pipe should be removed first to prevent the water meter from being blocked.
4. If the cold water meter is installed at the water inlet end of the boiler, it is necessary to prevent the hot water and steam backflow from damaging the water meter.
5. For the long-term use of water meter, the error changes due to the blockage of impurities and rust in the pipeline. Users are not allowed to destroy the lead seal by themselves, and can go to the water meter verification station for maintenance.
6. Select the specification of water meter according to the pipeline flow. It is better to use the flow rate close to or less than the common flow rate, and the diameter of the water meter cannot be determined by the diameter of the pipeline.
7. There are two kinds of water meter: dry type and wet type. It is normal that there is water and water vapor under the glass of wet water meter. In use, the old pipe, poor water quality or installed at the end of the pipe will cause rust pollution and affect meter reading.
8. The user is not allowed to disassemble and assemble the water meter sensor without authorization, so as to avoid affecting the metering accuracy of the remote water meter. If it is necessary to disassemble, please professional maintenance personnel.
9. When water is not used, if the meter moves slightly, it is caused by unstable water flow pressure in the pipeline or other reasons. Therefore, in order to prevent water backflow and affect the reliable operation of the equipment, check valve must be installed in front of the water meter.
10. When carrying the remote water meter, do not pull the wire directly, otherwise the core wire will be disconnected and the signal can not be sent out.
