Measuring device for the oversize of cleaning balls, having a version C piezoelectric dynamometer

摘要

Presented here, on the basis of the measurement of ball oversize, for the purpose of determining the efficiency of cleaning balls which are used in heat exchange systems is the invention of a measuring device in accordance with which an optimum solution of the problem has been found with the aid of fewer parts, which are of simple construction, by utilising piezoelectricity.
