ABSTRACT:
An apparatus for protecting and optically isolating the optical element of the probe used for sensing liquid levels includes a tubular body formed from a rigid, non-reflective material which slides over the optical probe. The probe is mounted within the tubular body to create a gap between the shield and the probe in which liquid collects. An open end of the tubular body is cut at an angle and tapers to a point at the widest part of the gap. The tapered point and gap width are arranged so that, when the liquid level falls below the probe end, the surface tension of liquid running down the tapered point overcomes the surface tension of the liquid in the gap and draws the fluid out of the shield.
