Abstract
The present invention provides a liner assembly for repairing the wall of a pipe that includes a transmitter or transmitters capable of transmitting information, such as identification information and physical characteristics of the area around the transmitter. Embedded in the liner is a transmitter, which includes a radio-frequency identification and at least one sensor. The RFID transmits identification information about the repaired wall, while the sensor provides physical characteristics of the environment in and around the pipe. Examples of physical characteristics may include temperature, pressure, flow, chemical reactions, velocity of the pipe, and the like. Additional transmitters may be used along the length of the pipe to determine characteristics at multiple locations, with each additional transmitter including the same or different sensors.
