Product Introduction

The Large-diameter Stainless Steel Mechanical Water Meter is a mechanical water meter with a full stainless steel structure, suitable for metering large flow rates in pipeline networks. It is widely used for water metering and management in municipal water supply, industrial pipelines, and agricultural irrigation systems.

Product Advantages

Enhanced Corrosion Resistance
Made of 304/316 stainless steel, resistant to acids and alkalis, rust-proof, suitable for complex water environments, and has a longer service life.

Stable Mechanical Structure
Power-free design, simple structure, and low failure rate.

Strong Resistance to Impurities
Wear-resistant impurity impurity + bearing design, adaptable to water containing sand and impurities, and more stable operation.

Application Areas

Municipal Water Supply Systems: Water metering and zoned management of urban main water supply networks

Industrial Water Systems: Flow monitoring and cost control of water used in factory production

Agricultural Irrigation: Water metering and quota management for farmland irrigation

Water Treatment Plants: Influent and effluent statistics and operational monitoring

Commercial Buildings: Total metering for large industrial parks/commercial complexes
