Abstract
Ultrasonic transducers are imbedded into sacrificial metal coupons which are located in the vicinity of underground or aboveground structures, such as a pipe or tank, which allow for the measurement of the effectiveness of impressed current cathodic protection systems and can be used to determine the corrosion rate of the structure that is being protected. When excited by a pulser-receiver excitation pulse, the ultrasonic transducers can be used to determine the thickness of the coupon and its rate of change over time. The sacrificial metal coupon ultrasonic transducer assembly can be located in the vicinity of underground piping, under or inside of a tank, underground or underwater, or inserted into structures where absolute material loss values or material loss rate of change is being monitored.
