    To meet the growing need for a portable instrument capable of accurately indicating water depths in wells and channels over a considerable range, the point gage was designed. As in other electric point gages, the distance of the water surface from a reference point is measured with a plumb-bob suspended on a graduated steel tape. Contact of the bob with the water surface closes an electric circuit, which activates the needle of a milliameter.
