FLUORESCENT OPTICAL LIQUID-LEVEL SENSOR Jonathan D. Weiss Sandia National Laboratories* Mail Stop 1081 P.O. BOX 5800 Albuquerque, New Mexico 87185-1081 tel: 505-845-8213 fax: 505-844-2991 ernai~:jdwe@%andia.~ov ABSTRACT An optical method of detecting liquid level is presented that uses fluorescence radiation generated in an impurity-doped glass or plastic slab. In operation, the slab is inserte...
متن کاملFiber-optic liquid-level continuous gauge
An intensity-based fiber-optic liquid-level gauge for continuous measurement is described. The sensing principle is based on the total internal reflection of light within the fiber optic, and for this, a measurement is made of the power attenuation which occurs in the fiber optic immersed in the liquid tank when the liquid level varies. The light from a LED is modulated before being directed in...
متن کاملFiber optic sensor for distributed liquid content quantification in subsurface
A novel fiber-optic sensor assembly for continuous monitoring of moisture over extended subsurface environments, such as road embankments, wall backfills, and landfills is presented. This sensor meets the requirements of subsurface monitoring by distributed measurements over linear positioning of a single fiber. The sensor assembly is composed of a communication optical fiber and a hydrophilic ...
متن کاملDiscrete bisoliton fiber laser
Dissipative solitons, which result from the intricate balance between dispersion and nonlinearity as well as gain and loss, are of the fundamental scientific interest and numerous important applications. Here, we report a fiber laser that generates bisoliton - two consecutive dissipative solitons that preserve a fixed separation between them. Deviations from this separation result in its restor...
متن کاملNew Measuring Method for Colorless Liquid Level Based on CLC100 Level Sensor and Powercast Wireless Sensor Kit
In this paper, a new wireless measuring method for colorless liquid level measurement was presented, based on latest CLC100 liquid level sensor and Powercast wireless sensor development kit. The wireless system is divided into two parts, level measurement and data transmission part as well as data receiving and display part. First part included the capacitive liquid level sensor CLC100 and the ...
