Device and method for measuring the volume of a cavity

摘要

Device (100) for measuring the inner volume V 1 of a cavity (1) comprising a hollow body (2) coupleable to said cavity (1), such that the inner volume V 1 of the cavity (1) and the inner volume of the hollow body (2) are communicated, comprising a solid body (3) housed in said hollow body (2), detection means (4) for detecting the position of said solid body (3), and processing means (5). Method for measuring the inner volume V 1 of a cavity (1) implemented in a device (100), wherein said inner volume V 1 is calculated from the oscillation of a solid body (3) according to the volume of gas inside said cavity (1).
