Philippi TCM Water Tank Monitor - Reading Backwards

[enjaku]

My name is Eric and I have a 2012-ish Philippi TCM water tank and fuel monitor on our Allures 45, I just replaced the float and sending unit in the starboard tank. With an empty tank, the monitor reads full, and as I add water the tank level on the Philippi monitor DECREASES. Any thoughts as to what may be going on here?

Cheers from Chicago.

Problem solved…. Sort of.
“ Apparently the euro version which you had originally read 240 ohms
(full) to 33 ohms (empty).

The US version which is the type of sender we installed reads 240 ohms
(empty) to 33 ohms (filled) so exactly the opposite”.

I think I can manually program the ohms into the tank monitor. We’ll see.
