1. Consider the convenience of installation and maintenance
This is especially important for large caliber water meters. Therefore, the water meters that can be installed and replaced without stopping water or repaired (such as removable water meters) can meet these requirements. The installation length and connection mode of the water meter is also a factor to be considered.
2. Cost-effective ratio of single flow meter
Purchase of any commodity requires consideration of its performance-price ratio. As a measuring instrument for trade settlement of water use, its performance-price ratio has its particularity.
3. Selecting Indicative Form of Single Stream Meter
Generally, wheeled reading is preferable, with clear reading and easy reading. But in the north, because the water meter in the water meter well is deep, the installation of pointer type is better. However, in recent years, newly developed water meters are digested and absorbed by imported water meters. They are basically liquid-sealed counters, which can be read by auxiliary methods.
4. Consideration of water quality adaptability
For various reasons, the water quality flowing through the water meter and to the water terminal in many cases is not as clean as that in the water treatment plant. Sometimes, there are some impurities (such as rust, sand, linen, etc.). In this case, in addition to the installation of some filters and other measures in the design of water meter pipelines, it is necessary to consider the selection of water meters or flowmeters that can adapt to such water quality.
