A system for distributing changing parameter information such as changing time, pressure, temperature, volume, velocity, density, flow, composition or like parameter information through a facility having an electrical gridwork with a plurality of outlets and a neutral or ground leg, comprising a source for generating coded electrical signals representative of changes in the parameter information, means at the facility for receiving the signals from the source and transmitting the signals in coded form through the facility on the leg as an antenna, and a plurality of signal employing means at the facility each connected to a respective one of the outlets and thereby coupled to the leg for receiving the same signals from the transmitting means representative of the same changes in the parameter information and carrying out same or different functions using said same signals.
