Abstract
The present invention relates to a fluid detection system which can be adapted for use in applications including liquid-level detection, pipeflow monitoring, and interstitial leakage in double-walled containers. The system operates on principles of optics and provides the capability of remotely differentiating between fluids having different refractive indices including liquids and vapors. The present detector uses a unique light pulsation technique which increases permissible operating ranges over existing optical detection systems.
