DMA zone metering

Zone metering management is a fine management mode that divides the whole urban public water supply network into several water supply areas to monitor flow, pressure, water quality and leakage point for quantification and effective control of the leakage area of the water supply network. Zone metering management divides the water supply network into multi-level zones step by step, and forms a network flow metering transmission system covering ex-factory metering, zone metering at all levels and user metering. It monitors and analyzes the flow change formats of each zone, evaluates the leakage of the pipe network and gives feedback in time and distributes responsibility for leakage monitoring, control and management of the pipe network to each zone for grid and fine management of water supply.

System functions

● Multi- level measurement zone drawing

● Binding of metering zone meters

● Calculation and analysis of meter leakage in metering zone

● Analysis of meter leakage ranking in metering zone

● Data analysis of meters belonging to the metering zone

DMA configuration management: it manually draws the metering zone by web gis map api, and binds the meters of the metering zone.

Data analysis of metering zone: it displays metering analysis and relevant metering points. The user can click pop-up window of any metering zone to display the daily water supply and consumption in the past week, calculate the daily apparent leakage rate according to the difference between the daily water supply and consumption, sum the water supply and consumption in the time interval and calculate the apparent leakage rate of the time interval. The user can click the analysis pop-up window of leakage rate in metering zone to display the total leakage rate of all metering zones in the past week.
