Abstract

PURPOSE: To detect the inclination of the measuring face based on the correlation of the back pressure values of both and detect the goodness or not of airtightness in a contactless manner by relatively fixing a reference pipe which spouts fluid onto the reference point on the measuring face and a detector which spouts fluid at a specified distance therefrom.
