Claim 15:
16. The pipeline monitoring system according to claim 15, wherein
each of the plurality of sensor devices transmits the measurement result from each of the plurality of magnetic sensors to the calculation device at an interval shorter than a transmission interval of the measurement result from each of the ultrasonic sensors, and
the second calculation unit calculates the value of ratio based on a measurement result most recently obtained from each of the ultrasonic sensors and a relative thickness obtained at a measurement position of the ultrasonic sensor in a relative thickness distribution most recently calculated by the first calculation unit, or calculates the value of ratio based on an absolute thickness most recently calculated by the third calculation unit at any position of the pipeline and a relative thickness obtained at the position in a relative thickness distribution most recently calculated by the first calculation unit.
