Abstract
A measuring device comprising: a sensor () with at least one electromechanical transducer (); at least one electrical generator connected to said transducer; and means for measuring the electrical input impedance of the transducer. Said sensor () has an empty space () passing therethrough within which a substance () can flow, and said transducer () is situated at the periphery of said empty space () in such a manner as to be subjected to a mechanical load characteristic of the substance () flowing in said space (), the measured electrical impedance being a function of said load. The device is suitable for use in a measuring apparatus seeking to determine the density of the substance () flowing inside said tubular space ().
