Figure 58. Albert sounder. The idea of Cardinal Cusanus, mentioned in the previous figure, was re-examined by the Italian architect Leo Battista Alberti and subsequentlydescribed by Giuseppe Biancani in 1635. The design was even simpler than Puhler's device. A simple rule of three was devised to derive the depth from the travel time to the bottom and return of the float.
