AI Technical Summary

Technical Problem

Water losses in the existing utility water distribution system were significant, and leak detection was a cumbersome and energy-intensive process requiring the installation of additional equipment and extensive manual work on-site.

Method used

The fluid consumption meter with an integrated noise detection module detects leaks by detecting acoustic noise in the pipeline system through an acoustic sensor. The two-way communication unit interacts with external devices to realize the leak detection mode of the fluid consumption meter and accurately locate leaks using timestamps and real-time data.

Benefits of technology

It simplifies the leak detection process, improves detection accuracy and efficiency, reduces energy consumption, and can accurately locate leaks in complex piping systems.

Abstract

The present invention relates to a fluid consumption meter (50) and a leakage detection system. The fluid consumption meter is configured to measure the flow rate of a fluid and includes a noise detection module (40) for leakage detection. The fluid consumption meter also includes a control device, which includes a two-way communication unit (60) and is configured to: receive a leakage detection control signal from an external device (100); set the fluid consumption meter (50) to a leakage detection mode when the leakage detection control signal is received; start noise detection for leakage detection in the leakage detection mode; and transmit data from the noise detection module.
