Abstract
Methods of maintaining accuracy in the measurement of one or more parameters of industrial water in industrial water systems are provided. The methods include the use of physical and/or chemical procedures to prevent and/or remove deposition from one or more surfaces utilized in measurement of the one or more parameters. The deposition may be caused by, for example, corrosion, fouling, or microbiological growth.
Claims20
A method comprising:
- contacting an industrial water stream at an industrial water stream pressure with a plurality of surfaces utilized for measuring a plurality of parameters of an industrial water in an industrial water system;
- isolating a first subset of the surfaces from the industrial water stream while a second subset of the surfaces maintains contact with the industrial water stream;
- cleaning at least one surface of the first subset of surfaces while the second subset of surfaces maintains contact with the industrial water stream;
- and
- restoring contact of the industrial water stream with the first subset of surfaces;
- wherein the first subset of the surfaces comprises at least one of a wetted surface of a pH sensor, a wetted surface of an oxidation-reduction potential sensor, and a wetted surface of a light transference medium;
- and
- wherein the second subset of the surfaces comprises at least one of a wetted surface of a corrosion detection sensor and a wetted surface of a conductivity sensor.
