Method for removing build-up on measurement gauges
First Claim
1. A method for cleaning a portion of a protective shield that is disposed within a conduit or aperture of a pipe, the pipe defining an inlet and an outlet, the conduit for passing fluid from the inlet to the outlet of the pipe, the protective shield containing a measuring device centrally disposed within the conduit of the pipe, the method comprising:
- providing a scraper disposed about at least a portion of the protective shield within the conduit;
applying an external force to the scraper to move the scraper within the conduit and longitudinally along the protective shield between first and second positions to thereby clean the portion of the protective shield over which the scraper moves.

Abstract
The present invention is directed to a device and method for removing build-up on such measurement gauges. The inventive device and method involve a movable scraper that fits around a cylindrical shield of a measurement gauge and continuously removes the build-up on the shield. Movement of the scraper is accomplished by a magnetic coupling between a magnetic core attached to the scraper, which is inside a pipe or other piece of equipment, and solenoids that are installed on the outside of the pipe. The device and method of the invention ensure instantaneously correct readings from the measurement gauge and improve control and operation strategies of heat exchanges, with significant economic advantages.
