Abstract : The patent relates to a fluid velocity indicator which includes a casing having fore and aft ends. A propeller shaft is rotatably mounted through the fore end of the casing with portions of the shaft extending exterior and interior the casing. A propeller is mounted on the exterior portion of the shaft, and a light source and a light sensor are mounted within the casing in a spaced apart relationship. Means are mounted on the interior portion of the propeller shaft and movable through the space between the light source and the light sensor for coding the light transmitted to the light sensor when the propeller is rotated by the fluid. In this manner light sensed by the light sensor will enable indication of velocity and direction of fluid flow passed the propeller.
