Water meters are classified by measurement level

According to the old standard, it can be divided into A-level meter, B-level meter, C-level meter, and D-level meter.

The measurement level reflects the working flow range of the water meter, especially the measurement performance under small flow. According to the order from low to high, they are generally divided into A-level meters, B-level meters, C-level meters, and D-level meters.

After the release of the new version of the standard, the classification method of the measurement level has become quite complicated, which is mainly determined according to various parameters such as flow value and range ratio. Simply put, the larger the range, the higher the measurement level.
