Abstract

Procedure and detector for the detection of an accidental rupture of a gas pipeline, the procedure characterized by measuring the temperature of the gas at a point in the pipeline, calculating the derivative of said temperature with respect to time, and detecting the appearance of a threshold of negative value of said derivative, which reveals the appearance of a break.
