thickness for annular plates

Does anyone know of a technique to measure the thickness of the annular plates in Aboveground Storage Tank within the critical zone (3") when entry to the tank can not be gained?

Re: thickness for annular plates The use of PEC (pulse eddy current) was initiated some years ago if I can recall it correctly. The probe is placed on the outer section of the annular plate and the signal transmitted will register thickness readings within the critical zone.
