摘要：Device for measuring or monitoring differences in level or variation indifferences in level between several points, comprising closed pots (2), respectivelyplaced at each one of the said points, these pots being partially filled with a liquid (53)

and being connected by liquid-carrying ducts emerging in their lower section in order toform a liquid circuit (31) and by gas-carrying ducts emerging in their upper section inorder to form a gas circuit (36), each pot being fitted with a capacitive proximity sensor(11) placed above and at a distance from the upper surface (54) of the liquid which itcontains and adapted to supply a signal for the position in the vertical direction of a zoneof this upper surface of the liquid in this pot, and means of comparing the signals

supplied by the said sensors in order to be able to supply vertical position information ofthe said pots, and consequently of the said points, with respect to each other or withrespect to a vertical reference position. ……
