Abstract
Apparatus for testing for leaks in a flexible package containing loosely packaged product and some air includes a first set of gravitational probes at a first measuring station for applying a load to the package and obtaining a first measure of the thickness of the package under this load, a second set of gravitational probes at a second measuring station for applying a corresponding load to the package in a corresponding position and direction with respect to the package and obtaining a second measure of the thickness of the package under the second load and means for comparing the first and second measures of thickness and for indicating the presence of a leak when the second measure is substantially less than the first.
