ABSTRACT:
A depth gauge from which lesser depths can be read off accurately on a scale which is expanded in the lower range. The expanded scale is achieved in that the component exposed to the pressure of the water is composed of at least two subcomponents, such as diaphragms or Bourdon tubes, which are subjected in succession to the effect of the water pressure.
