Abstract

Il comporte un tambour de bobinage 1 de fil 2 logé dans un compartiment monté à la partie supérieure d'un réservoir T de liquide L dont le niveau LL est à mesurer, un élément mobile 3, en fonction du niveau du liquide, fixé en bout du fil 2 et au moins une ouverture latérale 5, 6 dans une partie inférieure 4B du compartiment 4, sur laquelle est monté un couvercle 7A, 7B ; 7a, 7b à fenêtre transparente ou de contrôle lui-même éventuellement recouvert par un autre couvercle plein 8A, 8B. Application à la mesure et au contrôle de niveau de liquide d'un réservoir sous pression ou non. (CF DESSIN DANS BOPI)It comprises a winding drum 1 of wire 2 housed in a compartment mounted at the top of a reservoir T of liquid L whose level LL is to be measured, a mobile element 3, depending on the level of the liquid, fixed at the end wire 2 and at least one lateral opening 5, 6 in a lower part 4B of the compartment 4, on which a cover 7A, 7B is mounted; 7a, 7b with transparent window or control window itself optionally covered by another solid cover 8A, 8B. Application to the measurement and control of the liquid level of a pressurized or non-pressurized tank. (CF DRAWING IN BOPI)
