Gurus:

I have a new tool toy.  I needed to know the thickness of a tank wall (  steel ) with no ability to get to the other side of it.

Well, there's a tool for that!  So I  purchased an ultrasonic thickness gauge.  Figured I would test it out and return it if I was not happy.

Well, I am very happy with its performance and price.  $92.50 delivered to my door.

It is easy to test.   We all have lots of stuff that we can put our vernier calipers on and read to a fraction of a mm.
You just apply a little conducive juice to the sensing head ( it's included ) and look for the icon that shows you have a good marriage of the sensor and your material and read the thickness.  Sides need to be parallel for best results.

If I never use it again, it has paid for itself in peace of mind several times over.
I'll upload a couple pics below.

Very neat Russ.

Have used them for many years. Ship owners would have the crew or outside company do a grid pattern on the hull from inside, or outside with divers, and give the results to the USCG. Depending on hull thickness, Coast Guard would waive the annual drydock requirement and save the company many dollars, if hull thickness was over 75% of original.
Also used before drydock to get idea of amount of hull and bulkhead steel that needed replacement.

I had some rust and flaking from the bottom of my fuel tank. I needed to know how much metal was left. So I needed to compare the sides to the bottom. This tool did the job! Thankfully I am in good shape.

Did you have to empty the tank to test it?
Neat tool either way.

The tank was not empty and does not need to be. The difference in densities of the steel and fuel is sufficient to reflect a signal at the interface. Remember, even an "empty" tank is filled with air and again, it works on the difference in properties. Quite a tool for the cost!
