Abstract
An apparatus is provided for locating the level of liquids for particular use in volumetric dosage techniques. A probe is mounted upon a vertical column which slides axially in a slide fixed in the housing of the apparatus. Adjacent to the slide is a threaded rod rotatably mounted in the housing and a releasable nut which is integral with the vertical column and the threaded rod. The releasable nut permits engagement and disengagement of the vertical column and threaded rod. A drive mechanism connected to the vertical column is employed to control a potentiometer as a function of the position of the vertical column.
