ABSTRACT OF THE DISCLOSURE This invention relates to a liquid level measuring and recording apparatus which includes a recording stylus or pencil and a means for retaining a record such as marking paper. The stylus is connected to a float means which follows the level of the liquid and drives the stylus along the width of the paper in one direction when the level is rising and in the other direction when the level is falling. In addition, either the stylus or the paper are connected to rotating means which rotate in one direction only and which are also driven by the up and down movement of the float. As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the float is moving in the non-rotating direction, and a straight line at an angle to the first line, when the float is moving in the rotating direction. Preferably, the straight line is produced when the float is moving in an upward direction, and the straight line at an angle to the first line is produced when the float is moving in a downward direction. The rotating means can comprise a slip-clutch.
