Techniques for fluid control

A fluid level detection apparatus, comprising:

• a removable sensor housing configured to be mounted within or adjacent to a fluid-containing vessel;
• a float disposed within a chamber in the sensor housing, the float comprising a magnet;
• a magnetic switch positioned within the housing and operatively coupled to a processor;
• wherein movement of the float in response to fluid level changes causes the float magnet to interact with the magnetic switch, thereby activating or controlling one or more functions of the processor.

A system, comprising:

• a fluid control device, comprising:
• a valve configured to control a flow of fluid into a tank;
• a float operatively connected to the valve and configured to actuate the valve based on fluid level within a container;
• an activation lever configured to alter interaction with the float;
• and
• a fluid level detection apparatus, comprising:
• a removable sensor housing configured to be mounted within or adjacent to a fluid-containing vessel;
• a float disposed within a chamber in the sensor housing, the float comprising a magnet;
• a magnetic switch positioned within the housing and operatively coupled to a processor;
• wherein movement of the float in response to fluid level changes causes the float magnet to interact with the magnetic switch, thereby activating or controlling one or more functions of the processor.
