Abstract
A fluid level detection device for a chamber containing a fluid includes a sensor configured to indicate one of at least two states; a first state when a present fluid level in the chamber is above a threshold level with respect to a chamber floor, and a second state when the present fluid level in the chamber is below the threshold level. A stabilizer is configured to at least partially surround the sensor. The stabilizer includes a base portion and a plurality of sidewalls defining a storage well configured to store a portion of the fluid around the sensor. The stabilizer is configured to prevent the sensor from indicating the second state when a present fluid volume in the chamber is above a predetermined minimum amount. The stabilizer is configured to prevent the sensor from indicating a false 'low fluid' state during a non-stable event.
