A tank includes an interior magnetic float assembly for detecting a liquid level in the tank, and an exterior gauge component attached to a gauge head of the tank for detecting and indicating the liquid level of the tank based on a rotational orientation of a tank magnet of the magnetic float assembly. An adapter plate mounts a housing base of the exterior gauge component to the gauge head. The adapter plate is secured to the housing base and snaps onto the gauge head. A portion of the base defined by a first molded piece extends within an opening of the adapter plate and a second molded piece of the base extends from the opening away from the housing to define a proximal end portion of the housing disposed proximate the tank magnet. Alternatively, the base receives a threaded adapter for mounting to a threaded opening of a gauge head.

The invention is a rotational sensor to sense an object's angle and methods to analyze the sensor output. The sensor has a first emitting source, to either emit onto, or from the object, a first receiving sensor, to receive emissions from the first emitting source, either directly or indirectly, the emissions received dependent on said angle, first receiving sensor outputting a first signal a course measurement of the angle. Also present is a second emitting source, to emit onto, or from the object and a second receiving sensor, to receive emissions from the second emitting source, either directly or indirectly the emissions received again dependent on said angle, second receiving sensor outputting a second signal, as a fine measurement of the angle. A method of use of the sensor is disclosed together with a method of combining the fine and course measurements to output a signal with zero error.
