Leakage measurement
The i2O system measures and reports minimum night flows on a daily basis. Based on these measured minimum night flows, leakage estimates by DMA can also be reported daily
Implementing Advanced Pressure Management will significantly alter the night-day factor NDF used to convert night leakage (in m3/hour) into average daily leakage, using the Average Zone Pressure (P4). The i2O system uses its pressure data to automatically calculate the new NDF after installation and at regular intervals.
