Product Introduction
Large-diameter pipeline water meter featuring a screw-wing rotating shaft aligned parallel to the water flow direction; the counter dial is immersed in a specialized sealing fluid (liquid seal), while the meter mechanism directly contacts the pipeline water. This design combines a wet-type structure with a liquid seal, complying with the national standard GB/T 778. Key advantages include high flow capacity, low pressure loss, and suitability for continuous high-flow water supply in large-diameter pipelines. The wet-type gear transmission mechanism eliminates magnetic coupling, making the meter resistant to water leakage caused by external magnets (compared to dry-type magnetic water meters). The liquid-sealed silicone oil chamber ensures that the glass surface remains fog-free, free from water ingress, and resistant to scale buildup, guaranteeing clear meter readings over extended periods. This design resolves the common issue in conventional wet-type meters where the inner glass surface becomes contaminated, impairing readability. The meter mechanism is detachable, simplifying maintenance; the flange can be removed without interrupting pipeline operation to install pulse or photoelectric modules, enabling upgrades to remote transmission or NB-IoT smart master meters. ✅ Basic Technical Parameters (Cold Water Model): Nominal pressure: 1.0 MPa / 1.6 MPa; Medium temperature: Cold water ≤50 °C; (For hot water models, alternative precision grades may be selected); Pressure loss: ≤0.063 MPa under typical flow conditions; Installation: Horizontal installation, with the screw-wing axis aligned horizontally. ✅ Application Scenarios: Community inlet master meters, municipal pipeline branch lines, factories, hotels, and large-diameter main pipelines in commercial buildings—ideal for long-term, stable high-flow applications.
