Abstract
The present invention provides an apparatus for identifying irregular flow, at the entrance of hydrant outlet. The apparatus comprised of: a ring shaped housing having interface for connecting on one end the hydrant pipe end and on the other end to the hydrant outlet part, at least two flow detection sensors positioned in said ring shaped housing, located at predefined distance for each other, a processor for analyzing in real-time sensors measurements, by checking time differences between the detectors received signals and differences between measurements level of the detectors, wherein based on said analysis is determined if the liquid flow is in outward direction form the hydrant or in ward direction from into the hydrant and for calculating flow quantity and communication module for sending alerts based on the analyzed data.
