Abstract
An optical flow rate sensor system for a sprayer includes an optical sensor, an optical sensor window within a display housing, a rotary optical encoder device within a drum housing, and vortexing geometry upstream of the encoder device. The optical sensor is located adjacent to the optical sensor window. The encoder device has a unitary body, which comprises a main portion, a first tab portion, and a second tab portion. The encoder device is configured to revolve around an axis of the drum housing.
Claims19
A rotary optical encoder device comprising a unitary body, the body comprising:
- a main portion defining a first arcuate surface on a first side of the main portion and a second arcuate surface on a second opposite side of the main portion;
- a first tab portion extending from the second opposite side of the main portion proximate a first longitudinal end of the main portion, the first tab portion having a first inner surface and a first outer surface, the first outer surface extending from the first arcuate surface at the first longitudinal end of the main portion;
- and
- a second tab portion extending from the second opposite side of the main portion proximate a second longitudinal end of the main portion, the second tab portion having a second inner surface and a second outer surface, the second outer surface extending from the first arcuate surface at the second longitudinal end of the main portion;
- wherein the second arcuate surface of the main portion extends between the first inner surface and the second inner surface.
