Product Introduction

The Large-diameter Stainless Steel Water Meter is an industrial-grade water flow meter made of stainless steel, suitable for large-diameter pipes (DN50 and above), and widely used in municipal water supply, industrial circulating water and high-flow-rate metering scenarios.

Product Advantages

Highly Corrosion Resistant
Made of 304/316 stainless steel, offering strong corrosion resistance.

Impurity Resistant, Low Maintenance
Large diameter and wear-resistant structure reduce the risk of clogging and decrease the frequency of cleaning and maintenance.

Remote Transmission Support
Optional pulse, RS485, and NB-IoT for remote meter reading and data management.

Wide Metering Ratio
Metering ratio R80–R160, accommodating both low and high flow rates, adapting to fluctuating water usage.

Application Areas

Municipal: Main water supply meter
Industrial: Circulating water/cooling water monitoring
Agriculture: Irrigation water metering
Water Treatment: Influent/Outfluent water monitoring
Energy: Power plant/energy station water metering
