1) Has a long service life, and is highly resistant to high temperature.2) Elutes no hazardous substance, resists red and green rusts to prevent the water pollution, and is

hygienic over a long period of time. 3) With the coefficient of friction lower than a metal pipe, no scale is formed so as to maintain a constant

flow rate for a long time. 4) Light weight, convenient handling, simple cutting and easy installation

A wet-type multi-jet water meter uses the water entered into theinlet of the meter to create a jet of water through multiple portssurrounding an internal bottom chamber, and then to rotate animpeller. This water meter has a high sensitivity and a widemeasuring range.Each port has a nozzle to further increase the sensitivity of themeter, so as to effectively monitor the water losses.Introduces the power painting system to improve the surfaceappearance.The lid is rotated 360-degree to prevent it from being caught in aStyrofoam insulation

The indicating part is rotated 360-degree for an easy readingeven in a small space.The counter slopes 45-degree forward to facilitate a meterreading.A magnetic cover is integrally assembled to prevent the foreignsubstances from sticking to a magnet for a close contact.The engineering plastic material is used for a set of internalchambers to improve the endurance.
