Sight Glass Liquid and Vapor Recognition Device Using Light Reflection

Abstract

A liquid and vapor recognition device is described herein comprising a housing configured to connect to a sight port including a sight glass and including an interior reflective surface, a first circuit component comprising a plurality of light emitting diodes (LEDs) and a light sensor, the first circuit component being mounted within the housing proximate the sight glass with the interior reflective surface of the housing disposed opposite the LEDs, and a second circuit component mounted proximate the first circuit component, the second circuit component containing a plurality of analog to digital converters (ADCs). Reflections of the LEDs from the interior reflective surface are detected by the light sensor, and the light sensor communicates with the plurality of ADCs, which output a digital signal indicative of the intensity of the reflected light.
