Abstract
An oil level sensor assembly for an oil tank includes a cell with a first set of holes along the cell, an oil level sensor within the cell that is configured to be inserted into and removed from a bottom of the cell, and a ball valve column within the cell and adjacent to the oil level sensor. The ball valve column is rotatable, has ball valves that correspond with the first set of holes along the cell, and is configured such that the ball valve column is rotatable to an open position aligning the ball valves with the first set of holes to allow oil to access the oil level sensor and rotatable to a closed position misaligning the ball valves with the first set of holes to prevent oil from accessing the oil level sensor.
