Abstract

PURPOSE: To measure the leakage of an article to be measured regardless of the content volume of the article by a leakage measuring device by detecting the difference between the article and the internal pressure of a standard tank and varying the volume of volume varying means so that the difference may become zero.
CONSTITUTION: After the same pressure is applied into a standard tank 11 and an article 12 to be measured, two-way valves 18, 19 are closed to thereby detect the difference of the internal pressures between the tank 11 and the article 12 by a differenctial pressure detector 21. There is provided volume varying means 22 connected to the interior of the article and controlled by the detector 21 so that the detected differential pressure may become zero. The moved distance of the piston 24 represents the leaked amount of the article 12, and is indicated on an indicator meter 34.
