ABSTRACT:
A protective apparatus adapted for limiting corrosive effects of a liquid stored in a metallic storage tank. The apparatus includes anode means for carrying an impressed current to produce an electrolytic effect and inhibit corrosive interaction between the liquid and tank. Means for supplying electrical power is provided to the anode means and the anode means is supported from a side wall of the associated tank. Elastic members extend between the side wall and the anode means to maintain them in a submerged condition. Level compensator means includes a member having approximately neutral buoyancy so that it adds further weight to the apparatus as the liquid level decreases. Additionally, quick connect/disconnect means is provided to facilitate assembly and maintenance in existing and new storage tanks.
