Abstract

A method of measuring the amount of corrosion of a target material caused exposure to a fluid, over a period of time, utilizing a corrosion measuring device, including a resonator having a first surface area made of a material having a corrosion profile like that of the target material and having a second surface area made of material having a corrosion profile unlike that of the target material; and a transducer assembly, positioned to drive the resonator and sense resultant resonator motion, thereby producing a sense signal. In the method, the resonator is exposed to the target fluid over the period of time and the sense signal is analyzed over the period of time to determine changes in how the resonator responds to being driven by the transducer assembly, over time.
