TDC1000: How to perform liquid level sensing through the bottom of a metal tank

Thank you very much for your reply. I might not have been clear. I meant measuring through the metal at the top of the tank.  I’ve read posts that say the TDC1000 might not be the best transducer for this project.  I would also like to make it removeable. Would magnets adhere it to the metal top well enough to get a reading?
