摘要： For liquid-level sensing in a tank, the invention provides a tank-mounted first subassembly that is adapted for suspension of a vertical guide from the top of the tank, such that a guided float may coact with an elongate vertical ribbon, to angularly displace a magnetic element carried by the upper end of the ribbon. The tank-mounting of this first subassembly completes closure of the tank and its contents, and closure structure of this first subassembly assures containment of the ribbon and its magnetic element within the closed volume of the tank. A second subassembly of magnetically responsive electrical means is encapsulated by a housing which is detachably connectable to the closure structure of the first assembly, solely by access that is external to the closed tank. Electrical output of the second subassembly is flexibly available to remote indicating and/or monitoring circuitry which forms no part of the invention.

摘要： A method and system for remote monitoring of liquid level 21 within a container 12, such as the level of fuel within a propane cylinder. A magnetic float 20 disposed within the container 12 floats on the liquid 21, and lowers with the liquid level as fuel is consumed. Magnetic sensors 22 outside the container 12 sense the float 20 as it passes in the proximity of one of the sensors 22. A controller 26 receives output signals from the sensors 22 and transmits level indicating signals to a gauge 28 or other indicator for remote indication of the corresponding liquid level. The indicator 28 can be located proximal the user's direct line of sight, to remind the user to periodically monitor the fuel level to prevent running out of fuel.

摘要： Disclosed herein is an electronic float gauge for indicating the level of liquid in a tank. A float follows the liquid level and causes a rotor that has magnets on it to rotate. Surrounding the magnets, in a concentric array, are a series of reed switches. The rotation of the magnets feeds information to the reed switches about the level of fluid in the tank. The reed switches are connected to a fluid level indicator.
