Claim Text:
1. An optical sensor for a conventional tank gauge, comprising: an emitter circuit board comprising a plurality of photoemitters configured to emit a photon beam at a pre-determined wavelength; a detector circuit board comprising a plurality of photodetectors, wherein each member of the plurality of photodetectors is configured to produce an analog output when the photon beam is detected by the member of the plurality of photodetectors; an optical sensor frame, comprising an analog to digital converter configured to convert the analog output to a digital output; and one or more microcontrollers, configured to receive the digital output from the analog to digital converter and produce a tank liquid level measurement based upon the digital output; wherein the emitter circuit board and the detector circuit board are connected on opposite sides of the optical sensor frame such that the plurality of photoemitters are aligned with the plurality of photodetectors.
