Abstract
An improved turbidity sensor is provided with a pair of spaced apart arms respectively housing a light transmitter and a light receiver, with the receiver adapted to sense the light from the transmitter and generate a corresponding output signal. The opposing surfaces of the arms adjacent the transmitter and receiver are flame treated for approximately one second each so as to raise the surface energy such that bubble-induced noise is reduced or eliminated for a more accurate output signal.
