1Product Overview
Adopting the traditional rotor type mechanical water meter structure, it is used to measure the total volume of water flowing through the pipeline.DN15~25 water meters can be divided into two types of counters: wet and semi liquid sealed, while the rest of the calibers are wet counters.
IIProduct Features
l Mature technology and stable performanceThe water meter has high sensitivity.
l Unified national movement size designGood universality and interchangeability.
l The digital wheel of the semi liquid sealed water meter is sealed with a special liquid, which can maintain the clarity of the dial for a long time.
