Abstract: A level verification system for a radar level gauge utilizes a remotely positionable target. The target is positioned inside of a tank that is subject to level measurement, and stowed at a first position and selectively positionable to a second position to reflect emitted electromagnetic radiation in an amount indicative of a predetermined material level. The verification system can verify a high level alarm will be triggered when the material reaches a high level corresponding to the level of the target, by remotely positioning the target in front of the emitter of the radar gauge. The target reflects electromagnetic energy to the detector at approximately the same intensity that the material reaching the high level would reflect so as to provide an accurate verification.
