Abstract
1300160 Ultrasonic testing COMMISSARIAT A L’ENERGIE ATOMIQUE 4 Aug 1970 [18 Aug 1969] 37574/70 Heading H4D A device for measuring the position of a discontinuity in a fluid comprises two probes each including a piezo-electric transducer, a waveguide, a mirror reflecting sound waves from the waveguide on to a surface, said surface being for one probe a fixed reflector whose position is known and for the other probe the discontinuity; and a signal generator and receiver connected to the probes through a transmitreceive switch. The position of discontinuity 9, which may be an object or the fluid level, inside a nuclear reactor is determined by measuring the transit time, t, of n pulses from the waveguide 2 to the reflector. The other probe is used to measure the sound velocity, v, in the fluid. The displacement I is given by vt/2n. The transit times are measured by apparatus identical with that disclosed in Specification 1,300,159, a further changeoever switch being provided to connect the two probes alternately to the receiver. Tubes 10 are provided to prevent turbulence in the liquid sodium 5 across the measurement paths.
