Claim 6:
7. A system for indicating a possible leakage of gas or liquid from a transporting network containing a gas or liquid, comprising:
a flow input valve;
a pressure detector for measuring pressure and direction of the gas or liquid in the transporting network, wherein the pressure detector is positioned immediately upstream of the flow input valve; and
a controller for receiving and processing measurement data from the pressure detector to measure pressure by determining the amount of gas or liquid that passes through a point of measurement at a given time,
wherein the controller is to detect patterns of pressure over time at the point of measurement, and is further to detect a deviation in the patterns, and
wherein the pattern is a relatively fixed pressure over a period of time, and the deviation is a decrease of pressure below an expected fixed flow according to the pattern, the controller indicates a possible leak of gas or liquid from the transporting network.
