7 12A A wet-type multi-jet water meter uses the water entered into the inlet of the meter to create a jet of water through multiple ports surrounding an internal bottom chamber, and then to rotate an impeller. This water meter has a high sensitivity and a wide measuring range. Each port has a nozzle to further increase the sensitivity of the meter, so as to effectively monitor the water losses. Introduces the power painting system to improve the surface appearance. The lid is rotated 360-degree to prevent it from being caught in a Styrofoam insulation Size d L t 15A Item Wet-Type Multi-Jet Water Meter (MW) Overload Flow Rate(m 2 /h) Maximum Flow Rate(m 2 /h) Transition Flow Rate(m 2 /h) Minimum Flow Rate(m 2 /h) Startup Flow Rate(L/h) Maximum Operating Pressure(mpa) 1.47 Dimension Overall Length(L1) Height (H) Width (W) Pipe Size (D) PT 2 PT 4 PT1 PT14 PT1 2 PT2 15A The indicating part is rotated 360-degree for an easy reading even in a small space. The counter slopes 45-degree forward to facilitate a meter reading. A magnetic cover is integrally assembled to prevent the foreign substances from sticking to a magnet for a close contact. The engineering plastic material is used for a set of internal chambers to improve the endurance.

8 Grab Ring The material is stainless steel 316L that is remarkably resistant to the corrosion, and has a high grab strength at a high temperature. Retaining Cap The advanced material complies with the BS2462 standard in durability, the resistance to oxidation, heat and chemicals, electrical properties, a period to retain the elasticity and appearance.
