Description

The level measurement device includes two coils winded in one layer on the cover including the electricity conductor material. The coil turns surround the liquid metal and are imbricated each one related to the others and jointed. One of the coils is related to an alternating current feeding means with constant intensity and the other to a voltmeter. The voltage at voltmeter terminals is representative of the level or the volume of the conductor material in the cover. The conductor material may be liquid metal, metallic powder, on a conductor liquid of electrolyte type

Abstract (French)

Le dispositif de mesure de niveau comporte deux bobines enroulees en une seule couche sur l'enveloppe renfermant un materiau conducteur de l'electricite. Les spires des bobines entourent le metal liquide et sont imbriquees les unes par rapport aux autres et jointives. L'une des bobines est reliee a un moyen d'alimentation en courant alternatif a intensite constante et l'autre a un voltmetre. La tension aux bornes du voltmetre est representative du niveau ou du volume du materiau conducteur dans l'enveloppe. Le materiau conducteur peut etre un metal liquide, une poudre metallique ou un liquide conducteur du type electrolyte
