Automated Tank Cathodic Protection/Corrosion Monitoring System

摘要

An automated tank Cathodic/Corrosion Protection (CCP) monitoring system includes a mobile CCP data collection device. The data collection device can be moved horizontally to different locations in the tank. A reference electrode and corrosion coupon are lowered from the data collection device to desired depths within a liquid medium in the tank to collect data. The data collection device is connected to a programmable, external control unit enabling a operator to program a data collection schedule, the horizontal and vertical distance between readings, interruption of the system if the system is designed in a way to handle interruption, and has the ability to transmit the data remotely to a control center. These capabilities enable automated, remote monitoring of the CCP system, eliminate the safety concerns associated with sending technicians onto tank roofs, and give a more accurate and complete representation of the CCP system functionality and level of protection achieved.
