Multi-Jet Dry Type Water Meter

Product Overview

The multi-jet dry type water meter is a widely recognized mechanical water meter specially developed for residential and commercial water metering. As a classic velocity-type water meter, it adopts a multi-nozzle water inlet structure and a fully dry dial design. Different from wet type water meters, the counting mechanism is completely isolated from the measuring water, which effectively prevents internal fogging, water permeation and dial blurring. This meter maintains long-term clear reading visibility even after years of operation. With mature mechanical structure, reliable metering performance and affordable cost, it has become one of the most popular water meters for municipal water supply projects worldwide.

Working Principle

Tap water enters the meter chamber through uniformly distributed radial water jets. The multiple water streams impact the impeller evenly and drive it to rotate steadily at a speed proportional to the water flow rate. The rotation motion is transmitted to the dry counting mechanism through magnetic transmission technology. Since the register is completely separated from the water channel, impurities, sediment and water moisture cannot affect the counting system. Finally, the accurate water consumption data is displayed clearly on the sealed dial.

Structural Features

• Dry Dial Structure: The register is isolated from water to avoid fogging, condensation and blurring, ensuring permanent clear reading.
• Multi-jet Inlet Design: Even water flow distribution reduces impeller wear, improves running stability and enhances low-flow sensitivity.
• Magnetic Transmission System: Adopts non-contact magnetic driving to avoid mechanical friction, extending service life greatly.
• High-strength Housing: Available in brass or cast iron housing, featuring pressure resistance, anti-corrosion and anti-rust performance.
• Durable Internal Components: Precision engineered impeller, gear set and bearing ensure stable long-term operation.

Core Advantages

• High Metering Accuracy: Excellent response to low flow, effectively reducing water leakage and metering error.
• Low Maintenance Cost: No need for regular cleaning; the dry dial never gets foggy, minimizing after-sales maintenance.
• Strong Anti-interference Ability: Resists water hammer, pipeline pressure fluctuation and tiny impurities.
• Simple Installation: Horizontal installation requirement, easy pipeline matching for standard water supply systems.
• Energy Saving: Pure mechanical structure without power supply, zero energy consumption.

Application Scenarios

This multi-jet dry type water meter is mainly applicable for residential buildings, apartments, villas, rural water supply reconstruction projects, small shopping malls and general commercial buildings. It is perfectly suitable for clean tap water metering and meets the standard requirements of municipal water utilities. It can also be customized for different caliber sizes and connection standards to adapt to global market demands.

Technical Highlights

Compliant with international metering standards, stable measurement within the rated flow range, reliable performance under long-term continuous water flow conditions. With low failure rate and high cost performance, this meter is the ideal conventional metering solution for global water supply management companies.
