METHOD OF MEASURING DEGREE OF DIRTINESS OF SURFACES OF CONTAINERS Russian patent published in 2007 - IPC G01B7/06 

FIELD: measuring technique.

SUBSTANCE: method can be sued for measuring degree of dirtiness of surfaces of heat exchange of different heat exchangers including container with profiled shape as heat exchangers, radiators, shirts of cylinders units et cetera. Method includes in warming tested container up from heat source with permanent temperature till setting stationary temperature mode. Tested container is placed into tested bath filled with fluid. Fluid is subject to heating in tested bath to provide preset temperature strike onto tested container. As heat source for warming tested container up, saturated vapor is used produced by electrode vapor generator. Then convective heat exchange of tested container is measured by using ammeter and degree of dirtiness of surface of heat exchange of tested container is judged from relation of convective heat exchange of tested container to value of convective heat exchange of surface of heat exchange of reference sample.

EFFECT: improved speed of operation; improved precision of measurement.
