Water meter installation precautions
Water meter is a kind of flow measuring instrument, which is a measuring instrument for correct measurement and reasonable distribution of water resources. In order to ensure the accuracy of the water meter, in the market water meter products to implement mandatory inspection, strengthen supervision and management at the same time, should also pay attention to the installation and use of water meters and other aspects. The following is to share with you the water meter installation strategy.
01｜According to the model assembly
According to the installation method, the water meter is divided into horizontal type (H) and vertical type (V). To install according to the model, for the commonly used horizontal type water meter installation, it is required to install the water meter flatly, subject to the surface presenting a horizontal shape, and cannot be skewed. For vertical installation, the water meter should be ensured vertical, not crooked, slanted, twisted and other phenomena, otherwise it will affect the normal role of the water meter, resulting in the measurement of deviation and other situations.
02｜Watch out for the caliber of the water meter
When selecting the caliber of the water meter, in addition to considering the diameter of the pipe at the installation location, you also need to consider the size of the frequently used flow rate in order to select the appropriate caliber of the water meter. The best choice is to select a flow rate that is close to or less than the required flow rate of the water meter. The caliber of the water meter cannot be determined solely on the basis of the pipe diameter.
03｜Cleaning up internal and external impurities
At the time of installation, it is necessary to remove the debris in the pipeline, such as hemp wire, sand and gravel, etc., to ensure the safe use of the water meter. In addition, during long-term use, the water meter may be damaged by internal rust and scaling, and impurities in the pipeline, rust, etc. may also clog the water meter filter or enter the inside of the meter to affect measurement. It is recommended to replace the water meter or re-clean and test the water meter within 6 years of its use as stipulated by the state.
04｜Attention to the installation occasion
When installing a water meter, you should choose a location that is easy to remove and install and read the meter, and prevent direct sunlight and icing. In addition, a valve should be installed before the installation of the water meter to disconnect the water and facilitate the removal of the water meter. When selecting a location for meter installation, it is important to consider that the water pressure and water temperature used are within the maximum operating pressure and maximum operating temperature of the meter. For installation in boilers and other places where hot water is used, the cold water meter should prevent hot water from flowing back and scalding the movement.
