System for determining the level of a liquid in a container

A system for determining the level of a liquid in a container, the system comprising:

• (a) a first fluid conduit, the first fluid conduit comprising a distal end and a first proximal end, the first fluid conduit being appropriately dimensioned so that, when the distal end is inserted into the container and is situated proximate to the bottom of the container, the first proximal end is situated outside of the container;
• (b) a pressure transducer, the pressure transducer being operatively coupled to the first proximal end of the first fluid conduit so as to emit a signal proportional in amplitude to the fluid pressure head in the container;
• (c) a processor operatively coupled to the pressure transducer to receive the signal emitted by the pressure transducer and to determine the liquid level in the container based on the signal;
• and
• (d) a user interface module operatively coupled to the processor, the user interface module comprising at least one user-accessible input control and at least one user-perceptible notification device.

A system for determining the level of a liquid in one or more of a plurality of containers, the system comprising:

• (a) a plurality of fluid conduits, each of the fluid conduits comprising a distal end and a first proximal end and being appropriately dimensioned so that, when the distal end is inserted into a container and is situated proximate to the bottom of the container, the first proximal end is situated outside of the container;
• (b) a corresponding plurality of pressure transducers, each of the pressure transducers being operatively coupled to the first proximal end of a different one of the fluid conduits so as to emit a signal proportional in amplitude to the fluid pressure head in a corresponding container;
• (c) a processor operatively coupled to the pressure transducers to receive the signals emitted by the pressure transducers and to determine the liquid level in the containers based on the signals;
• and
• (d) a user interface module operatively coupled to the processor, the user interface module comprising at least one user-perceptible notification device for communicating the liquid level in at least one of the containers.

• (d) a processor operatively coupled to the pressure transducer to receive the signal emitted by the pressure transducer and to determine the liquid level in a container based on the signal;
• and
• (e) a user interface module operatively coupled to the processor, the user interface module comprising at least one user-perceptible notification device for communicating the liquid level in at least one of the containers.
