Abstract:
Provided is a water leakage detection method for detecting water leakage of a water pipe by a water leakage detection apparatus that includes a processor and a display device. The method includes: a first procedure of the processor acquiring a water leakage detection result of the water pipe in a district metered area, the district metered area being a range to be measured by a flow meter; a second procedure of the processor acquiring a water leakage detection result of the water pipe obtained based on measurement data of a vibration sensor terminal attached to the water pipe; and a third procedure of the processor outputting, a screen for displaying the water leakage detection result obtained based on the measurement data of the flow meter together with the water leakage detection result obtained.
