Abstract
A apparatus for sensing fluid parameters such as optical density, light transmittance, electrical conductivity and/or other characteristics of a fluid, including an emitter adapted to project a light beam and an electrical current and a detector adapted to transmit a first signal in response to receiving the light beam and a second signal in response to receiving the electrical current. A processor determines a set of fluid parameters according to the signals transmitted from the detector. A measured amount of diluent may be added to the fluid to increase light transmittance and/or electrical conductivity so as to enhance sensor operation and sensitivity.
