Abstract
A method and apparatuses to make an in-service measurement of the thickness and corrosion rate of the floor an aboveground or bulk underground storage tank. The preferred method is to use an off-the-shelf ultrasonic sensor that is placed on the end of a staff and inserted into an opening at the top of the tank to make one or more local measurements of the thickness and corrosion rate of the tank floor. When combined with the results of a previous out-of service internal inspection of the floor or an acoustic emission (AE) corrosion activity test performed with a vertical and horizontal array of three or more AE sensors placed on a staff and inserted into the liquid or on the external wall of the tank and show almost no corrosion activity, these local measurements can be used to determine the thickness and corrosion rate for the entire tank floor.
