Le principe du variomètre repose sur la mesure de variation de la pression atmosphérique lors d'une montée ou d'une descente. Pour ce faire, un variomètre est constitué par exemple d'une capsule manométrique reliée à un réservoir isolé thermiquement, l'ensemble étant mis en relation avec l'air libre (atmosphère ambiante) par l'intermédiaire d'un tube capillaire calibré.
