Abstract
An apparatus may include: a body defining a flow path; an inlet to the flow path; an outlet to the flow path; a test coupon at least partially disposed within the flow path; a sealing element disposed between the test coupon and the body; and a current source electrically coupled to the test coupon, wherein the inlet and the outlet are in fluid communication through the flow path, and wherein the sealing element electrically insulates the body and the test coupon.
Claims17
An apparatus comprising:
- a body defining a flow path;
- an inlet to the flow path;
- an outlet to the flow path;
- a first thermocouple for measuring a first temperature of a fluid in the inlet to the flow path;
- a second thermocouple for measuring a second temperature of the fluid in the outlet to the flow path;
- a test coupon at least partially disposed within the flow path;
- a sealing element disposed between the test coupon and the body;
- a current source electrically coupled to the test coupon, wherein the current source is configured to flow current through the test coupon;
- and
- a programmable logic controller for adjusting the current flowing through the test coupon based at least in part on the first temperature and/or the second temperature;
- wherein the inlet and the outlet are in fluid communication through the flow path, and wherein the sealing element electrically insulates the body and the test coupon.
8 more elements
A method of corrosion monitoring comprising:
- weighing a test coupon to determine a first weight;
- inserting the test coupon into a flow path defined by a body, wherein one or more sealing elements are disposed between the test coupon and the body;
- flowing a fluid from an inlet of the body, through the flow path, and to an outlet of the body such that the fluid contacts the test coupon;
- flowing current through the test coupon while flowing the fluid to heat the test coupon;
- measuring a first temperature of the fluid before the fluid enters the inlet and measuring a second temperature of the fluid after the fluid exits the outlet;
- adjusting the current flowing through the test coupon based at least in part on the first temperature and/or the second temperature;
- and
- thereafter, weighing the test coupon to determine a second weight.

A system comprising:
- a corrosion monitoring apparatus comprising:
- a body defining a flow path;
- an inlet to the flow path;
- an outlet to the flow path;
- a first thermocouple for measuring a first temperature of a fluid in the inlet to the flow path;
- a second thermocouple for measuring a second temperature of the fluid in the outlet to the flow path;
- a test coupon at least partially disposed within the flow path;
- a sealing element disposed between the test coupon and the body;
- and
- a current source electrically coupled to the test coupon,
- wherein the inlet and the outlet are in fluid communication through the flow path, wherein the sealing element electrically insulates the body and the test coupon, wherein the current source supplies current to the test coupon, and wherein the current source comprises control circuitry capable of varying current supplied to the test coupon;
- and
- a control system comprising a programmable logic controller configured to provide a control signal to the current source, wherein the control system is configured to adjust the current flowing through the test coupon based at least in part on the first temperature and/or the second temperature.
