Ultrasonic Water Meter (Large Diameter)

Large-diameter ultrasonic water meter designed for high-accuracy measurement in municipal and large-scale water supply systems. It is suitable for applications requiring precise metering, trade settlement and system-level data collection.

Based on the time-difference measurement principle, the meter uses ultrasonic transducers installed upstream and downstream to calculate flow by detecting the propagation time difference of ultrasonic signals in water. This enables accurate and stable measurement without mechanical wear.

The meter supports communication modules such as Cat.1, NB-IoT and LoRa, allowing integration with centralized systems and cloud platforms for remote data transmission and monitoring.

Designed for long-term reliability and low maintenance, the solution is suitable for large-diameter pipelines and infrastructure environments requiring high precision and scalable deployment.

Product Features

◎High precision and wide range, R=800, 630, 500, 400, 315, 250, 200; Q₂/Q₁: 1.6;

◎High flow ability, no moving parts inside, no blockage, and low pressure loss;

◎Low starting flow, 0.016m³/h (DN50), much lower than mechanical water meters

◎High stability design, effective application of neural networks, forming a closed-loop effective processing system;

◎Anti-disturbance flow design: unique flow channel design combined with special multi-channel algorithm to achieve U0D0;

◎Low power consumption design: optimized hardware and software, built-in lithium battery with a service life of up to 10 years, no need to replace the battery during the period;

◎Anti-fouling design: adaptive adjustment of signal acquisition data to achieve zero impact of fouling on signals;

◎Anti-bubble design, real-time tracking of measurement data, combined with powerful data caching, can track fluid states under different states to achieve accurate metering;

◎Anti-surge design, effectively preventing metering errors caused by long-term non-use or insufficient pipe filling;

◎IP68 protection grade design, modular glue sealing, integrated with mechanical sealing to achieve 360° waterproof design;

◎Anti-disassembly design, hidden fixing screws, glue sealing at joints, and plastic lead sealing to prevent damage;

◎Easy to install, U0D0; can be installed at any angle.
