Abstract

A control system for generating and utilizing at least one or more addressed datagrams that communicate information to and from devices along piping assemblies comprising; one or more transmitters, one or more receivers, and one or more controllers and/or transponders wherein the transmitters transmit information via one or more addressed datagrams encoded within a fluid medium to one or more receivers among the piping assemblies, is described. Transmitters or transponders convert datagrams into signals that are transmitted within the fluid medium and the receivers receive signals from the transmitters and also convert signals from the fluid medium which is converted back into datagrams. The controllers receive and decode the datagrams so that the controllers selectively communicate and perform logical operations on piping assembly devices according to directions received from the addressed datagrams. The entire control system can function as a network of controllers, receivers, transmitters, and/or transponders as required by one or more users.
