In one embodiment, a sensor assembly 110 includes at least one optical fiber 114, 116 adapted to at least one of transmit and receive an optical signal, and a moveable float member 124. The float member 124 is adapted to move in a first direction as the fluid level increases and in a second direction as the fluid level decreases. The float member 124 blocks the optical signal at a first value of the fluid level, and allows the optical signal to pass at a second value of the fluid level. The presence or absence of the optical signal is detected to determine the level of fluid. For measuring fuel levels within fuel tanks.
