Patent Images
1. A corrosion measurement system, comprising:
- a corrosion sensor having a corrosion sensor output related to corrosion due to exposure to a process fluid;
a process variable sensor having a process variable output related to a process variable of the process fluid wherein the process variable changes a rate at which components exposed to the process fluid corrode; and
measurement circuitry coupled to the corrosion sensor and the process variable sensor having an output related to corrosion of components exposed to the process fluid based upon the corrosion sensor output and the process variable output wherein the measurement circuitry identifies periods of reduced corrosion rate and uses reduced power during the periods of reduced corrosion rate.

Abstract
A corrosion measurement system includes a corrosion sensor having a corrosion sensor output related to corrosion due to exposure to a process fluid. A process variable sensor provides a process variable output related to a process variable of the process fluid. Measurement circuitry coupled to the corrosion sensor and the process variable sensor provides an output related to corrosion based upon the corrosion sensor output and the process variable output.
