● 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.
