Description

Technical Field

[0001] This utility model belongs to the field of water monitoring technology, specifically relating to a DMA zone metering device. Background Technology

[0002] DMA (Digital Metered Area) is a water loss control method for urban water supply systems proposed by the UK Water Industries Association in the early 1980s. It divides the pipe network into independent areas by closing valves or installing flow meters, monitors flow in real time and analyzes leakage levels, and actively controls leakage by combining measures such as nighttime minimum flow monitoring and pressure management.

[0003] DMA (Districted Area Management) zones are divided into large, medium, and small sizes based on the number of users, and into three categories based on pipeline type: water supply pipes, water distribution pipes, and stacked pipes. The implementation process includes steps such as zone division, closure testing, and hydraulic model analysis, requiring a balance between construction costs and water quality risks. Therefore, this application provides a DMA zone metering device, based on traditional DMA zone metering devices, to achieve real-time water volume monitoring and leakage quantification.
