Method and system for stamping and marking fluid in a pipe network for smart monitoring systems

摘要

The invention provides a system and method for determining fluid flow in a fluid pipe network. One or more markers are installed a various locations on the pipe network. Each marker generates an alteration in one or both of an initial fluid flow and an initial fluid pressure at the marking location of the marker. The alteration is characterized by one or more parameters whose values are indicative of one or both of the initial fluid flow and the initial fluid pressure at the marking location of the marker. One or more sensors are also installed on the network that detect one or both of a fluid pressure or a fluid flow rate at one or more sensing locations in the pipe network and generate a signal indicative of one or both of the fluid pressure and the fluid flow rate at the sensing location of the sensor. A processor analyzes the signal generated by each sensor to determine one or both of the initial fluid flow rate and initial fluid pressure at the marking locations.

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:
i) an integral energy source;ii) a fluid pressure in the pipe network; andiii) a fluid flow in the pipe network; (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.
