ABSTRACT:
A liquid level detector includes a pivotally mounted bent arm which supports, adjacent opposite ends thereof, a float and a component of a signal generator. As the level of a fluid contacted by the float rises and falls, the opposite end of the arm will move into proximity to or away from a support. The second component of the signal generator is mounted on the support and a signal indicative of the juxtapositioning of the second end of the arm to the float will be generated.
