ABSTRACT:
The invention contemplates remotely operable lifting mechanism for selectively displacing a liquid-level float in a sealed tank, to permit checking of the operational status of the float throughout its displaceable range, and to permit check-out of magnetically operated electrical means actuated by the float at a predetermined float level within its displaceable range. The lifting force is coupled magnetically to the float without interference with the path of float movement and without interference with the magnetically operated electrical means.
