ABSTRACT:
Only one pressure sensor is employed in a compact measuring apparatus for measuring both depths of water and altitude. A pressure-data generator generates pressure data corresponding to a pressure applied to the single pressure sensor. A water-depth data converter converts this pressure data into water-depth data. An altitude-data converter converts this pressure data into altitude data. The water-depth data and the altitude data are visually displayed on the compact measuring apparatus.
