Abstract
Introduced in this paper is a fiber optic gauging technique with millimeter accuracy for river level measurement. It plays an important part in flood-control season. The principle of operation and structure are illustrated. In order to ensure the reliability and to keep the millimeter accuracy in 16-meter range of fluctuation, some key techniques in optic, mechanism and electronics of this gauge are discussed in detail in this paper.
