Corrosion monitoring method and device

The invention relates to the technical field of corrosion monitoring, in particular to a corrosion monitoring method and device.The corrosion monitoring method comprises the steps that a plurality of monitoring point positions are determined and arranged at intervals in the flowing direction of fluid, resistance probes are installed on the monitoring point positions respectively, test pieces of the resistance probes make contact with the fluid, and the test pieces of the resistance probes make contact with the fluid. The plurality of resistance probes are electrified, the initial resistance values of the plurality of resistance probes are recorded respectively, the real-time resistance values of the plurality of resistance probes are monitored, the real-time corrosion rate of each monitoring point position is obtained according to the initial resistance values and the real-time resistance values of the resistance probes, and the average corrosion rate and the average corrosion rate are determined according to
