摘要: A apparatus (1) for sensing flow and/or other characteristics of a fluid, including an emitter (14) for projecting a light beam, a detector (16) for transmitting a signal in response to light received, and a rotatable member (6,10,12) for transmitting the beam of light from the emitter to the detector through a quantity of the fluid. Optic fibers/light pipes (18,20) may be used to transmit light to the emitter from a light source, and from the detector to a processor remote from the detector. The rotatable member may include optic fibers (10,12) to transmit light therethrough or alternatively reflective and nonreflective zones (291,292) for redirecting light to the detector (Fig.6). In either embodiment, light passes through the fluid to the detector. In another embodiment, the rotatable member may have a plurality of light pipes, and blades.
