Abstract:
     The related fuel handling technique for a ball-bed reactor comprises: dividing the dual-way ball-over counter designed on the vortex sensor into A and B opposite respectively to LA and LB of vertex sensor coils, and changing the drive signal from original fixed-frequency constant voltage source into variable-frequency one by the series a signal generator, an impedance-voltage conversion circuit and a signal check circuit. This invention increases obviously the amplitude of over-ball signal, and reduces mutual inductance effect between coils efficiently.
