Abstract
The present invention relates to a device for detecting the level of liquid in a tank. The device comprises a level detector formed of two arms pivoted on a common fixed support about first, respectively parallel, generally horizontal axes and a movable support member carrying a float adapted to follow the level of the liquid, the support member being pivoted on the two arms about second axes respectively spaced from but generally parallel to the first axes, in order that on change of level of the liquid the float follows a curved path determined by the combined pivoting of the arms, the float cooperating with a transducer adapted to generate a signal representing the position of the float.
