1. A remote monitoring adapter for use with a levelmeter having a magnet that moves in response to varying levels of liquid in a container, comprising:

  • a probe having a thin flat plate for placement proximate to the magnet and having a first hall sensor mounted on the plate operable to respond to motion of the magnet;

    a processing unit that receives an output signal from the first hall sensor and converts it to digital level data;

    a transmitter operable to receive the digital level data and to generate a remotely transmittable signal containing the digital level data; and

    wherein the first hall sensor and a second hall sensor are positioned a distance apart and relative to the magnet such that the processing unit calculates a rate of consumption, and wherein the digital level data represents the rate of consumption.
