Abstract: The present invention relates to a method and to a device for testing a partly conductive medium to determine a characteristic thereof. A signal generator generates a periodic excitation signal in a resonant circuit, including a coil which produces a magnetic field, which is coupled to the partially conductive medium. Eddy currents induced in the partially conductive medium cause the current flowing in the resonant circuit to vary. The amplitude of the envelope of the current flowing in the resonant circuit is measured and processed to determine the characteristic of the medium.

Abstract: A tubular piezo-electric sensor has at least one sensitive element disposed against an outer surface of a tubular support. A substance whose acoustic impedance is very different from that of the material forming the tubular support is disposed therein and a remaining volume of the tubular support is filled with liquid. Glass fiber cords or open cell foams, for example, are used as the substance, and the liquid may, for example, be that which fills a seismic streamer and, in this case, the tubular support is left open. The tubular support may also be closed at both ends by sealed caps and included in a protective sheath. The dimensions of the tubular support and the material from which it is made are chosen so as to optimize the sensitivity of the piezo-electric sensor.

Abstract: A process and device for measuring the velocity of flow of a fluid stream by measuring the difference between the respective traveltimes of acoustic pulses emitted by means of a generator (G) respectively between two points (PA, PB) spaced out along the fluid stream, according to whether they are propagated upstream or downstream in relation to the direction of flow, a difference that is indicative of the displacement velocity of the fluid stream. Measurement of this traveltime difference comprises using an acquisition unit (A) coupled to a processing unit (P) allowing determination of the frequency spectrum of each pulse and measurement of the phase lag affecting at least part of the frequency spectrum of each pulse, resulting from the traveltime thereof. Measurement of the velocity of flow of the fluid stream and of the resulting flow rate is very accurate. The process can be applied in chemical industries, chromatography, etc.

Abstract: In order to measure for example the velocity of particles moving within various pipes or enclosures (1), such as catalyst balls circulating in continuous reforming plants, a channel (2) with a section suited to that of the particles, connected to a source of fluid of determined flow rate (4), opens therein and the pressure variations in this channel, resulting from the flow of the particles circulating past the end thereof, which modify the free flowing of the fluid towards the pipe, are measured. The particle velocity is notably determined through an auto-correlation of the signal translating the pressure variations by means of a processing system (6). Two fluid-fed channels (7, 8) may also open onto two different locations along the pipe and, through a crosscorrelation of the signals translating respectively the pressure variations, the velocity and the section of the circulating particles may for example be determined.
