Recently I observed a stainless steel rod with a magnet encased in a stainless steel ball which moved up down the rod as the fluid level changed. The changes in the level was recorded via galvanometre.
I would like to construct such an item but not sure of the circuitry. Can someone point me in the right direction . Thanks.
