ABSTRACT:
An apparatus and method continuously samples and measures the changing concentration and/or density of suspended solids in a liquid medium without electrical connections at the submerged points in the liquid. A submersible sensing head is connected by an elongate probe to an non-submersible enclosure which contains at least one light source and one light detector. The sensing head has an apertured sample chamber allowing liquid to flow freely therethrough when submerged and contains at least one light emitting lens and at least one light receiving lens aligned in the flow path. The light emitting lens is connected to the light source and the light receiving lens is connected to the light detector with fiber optic bundles extending the probe. An elongate shaft extends through the probe and into the sensing head sample chamber and has a lens wiper at its lower end. The shaft is reciprocated by a timed motor in the enclosure to move the lens wiper between the lenses to wipe them clean of debris at selective continuous or intermittent cycles. When the sensing head is submerged light is transmitted from the light source to the emitting lens through the liquid between the lenses to the receiving lens and to the light detector for determining the concentration and/or density of suspended solids in the sample liquid with no submerged electrical connections.
