A large number of liquid nitrogen flU systems have been described in the literature which satisfy a wide range of experimental requirements ~'~. There have not, however, been any descriptions of simple flu systems which provide a rapid, precise regulation of the liquid nitrogen level for widely-diff

## Abstract An all optical fiber, intensity modulated sensor for discrete liquid level sensing is presented. The highly sensitive and robust design requires only silica fibers, an optical source and a detector. The sensor probe is prepared by etching the silica fibers using hydrofluoric acid. Exper
## Abstract In this article, a simple intensityβmodulated fiber optic sensor for liquid level measurement is presented. The sensor principle is based on frustrated total internal reflection effect caused by refractive index change of a medium surrounding an optical fiber. The end face of a stepβind
## Abstract This article reports the principle of operation, design aspects, experimentation, and performance of a noncontact fiber optic liquid level sensor. The sensor is based on the phenomenon of reflective concept. The device consists of fiber optic transmitter, fiber optic probe, floating ref
