The procedure is then repeated with other sets of emitting and receiving elements on an identically arranged assembly of measuring probes or alternatively arranged assembly of measuring probes moved forward or inserted into another passage opening(s) of the product, until a required amount of measurements enabling to analyse openness of requisite amount of passages in the whole inspected product is achieved, wherein individual assemblies of measuring probes are designed so that the routes between all designed pairs of emitting element-receiving element cover sufficient amount of passages for evaluation of the analysed product. | 01-17-2013 |
