CA 2172895

A water well bored into the earth, the well having a well casing extending below a water level to the bottom of the well, is provided in combination with a continuous water level indicator. Such continuous water level indicator includes a float which is adapted to float, as well as to rise and fall unhindered as the level of the water in the well rises and falls. A tube extends outwardly adjacent the top of the well from the well to the interior of a dwelling. An indicator is provided which includes a dial and a spring-loaded pointer which is movable to different indicia on the dial of the indicator. A pulley is provided at the junction of the well casing and the tube. A lightweight operating filament is provided, one end of which is connected to the upper end of the float, the intermediate portions being movable in a frictionless manner with respect to the well casing and the tube, and the other end being connected to the pointer. The strength of the spring is selected to be exactly equal to the buoyant weight of the float, so that, as the float rises and falls, the pointer moves to indicate water level.

Puits d'eau foré dans le sol. Le puits ayant un tubage s'étendant sous un niveau phréatique jusqu'au fond du puits comprend un indicateur continu du niveau d'eau. Cet indicateur comprend un flotteur destiné à flotter, ainsi qu'à monter et à descendre sans entraves au fur et à mesure que le niveau de l'eau dans le puits monte et descend. Un tube s'étend vers l'extérieur dans le voisinage de l'orifice du puits, à partir du puits jusqu'à l'intérieur d'une habitation. Il y a un indicateur comprenant un cadran et une aiguille montée sur un ressort qui se déplace jusqu'aux différentes indications sur le cadran. Une poulie se trouve à la jonction du tubage du puits et du tube. Un filament de mesure de faible poids est fourni, un de ses bouts est relié à l'extrémité supérieure du flotteur, ses parties intermédiaires sont mobiles de manière à ne pas frotter ni sur le tubage du puits ni sur le tube, et l'autre bout est relié à l'aiguille. La tension du ressort est choisie de manière à correspondre exactement à la densité immergée du flotteur, de sorte que, lorsque le flotteur monte et baisse, l'aiguille se déplace pour indiquer le niveau de l'eau.
