Abstract
A corrosion rate measurement system includes a first membrane of a first material configured to be exposed to a corrosive material and deflect in response to corrosion. A second membrane is configured to be exposed to a corrosive material and deflect in response to corrosion. A pressure sensor is operably coupled to at least one of the first and second membranes and configured to measure deflection of at least one of the first and second membranes as a function of a pressure and an amount of corrosion at least one of the first and second membranes.
