Abstract
Systems and methods described herein allow for reliable and computationally efficient detection of fluid leak events or abnormal fluid usage/flow events. A fluid flow meter can measure fluid flow parameter values during a training phase. The fluid flow meter can generate, using the fluid flow parameter data, a training fluid flow duration pattern indicative of, for each value range of a plurality of value ranges of a respective time threshold value. The time threshold value can represent an estimate of a maximum fluid flow duration, within a given fluid flow event, for fluid flow associated with the corresponding value range. During a detection phase, the fluid flow meter can determine, for a value range, a respective fluid flow duration within a current fluid flow event. The fluid flow meter can detect a leak event upon the fluid flow duration exceeds the time threshold value for the same value range.
