Claim Text:
1. A system for determining fluid flow in a fluid pipe network comprising: (a) a plurality of fluid parameter altering modulators, each marker modulator adapted to generate an alteration in one or both of an initial fluid flow and an initial fluid pressure at a modulating location in the pipe network, the alteration being characterized by one or more predetermined parameters, the values of the one or more parameters being indicative of one or both of the initial fluid flow and the initial fluid pressure at the modulating location of the modulator, wherein the alteration generated in the initial flow rate or pressure is selected from a frequency modulated wave, an amplitude modulated wave, or a phase modulated wave; wherein each of said plurality of modulators is activated by one of the following: (b) one or more sensors adapted to detect one or both of a fluid pressure or a fluid flow rate at one or more sensing locations in the pipe network and to generate a time dependent signal indicative of one or both of the fluid pressure and the fluid flow rate at the sensing location of the sensor; and (c) a processor configured to analyze the signal generated by each of one or more of the sensors to determine one or both of the initial fluid flow rate and initial fluid pressure at one or more of the marking locations.
