Self-compensating fiber optic flow sensor having an end of a fiber optics element and a reflective surface within a tube
Patent
·
OSTI ID:1175744
A flow rate fiber optic transducer is made self-compensating for both temperature and pressure by using preferably well-matched integral Fabry-Perot sensors symmetrically located around a cantilever-like structure. Common mode rejection signal processing of the outputs allows substantially all effects of both temperature and pressure to be compensated. Additionally, the integral sensors can individually be made insensitive to temperature.
