Distributed liquid level sensors using self-heated optical fibers for cryogenic liquid management.
We present a continuous liquid level sensing system for both room temperature and cryogenic fluids with millimeter spatial resolution. Change of in-fiber Rayleigh backscattering signal from the distinct thermal response of the heated sensing fiber in liquid and in air were interrogated and spatially resolved using the optical frequency domain reflectometry. Both electrical and optical heating t...
متن کاملVirtual Techniques for Liquid Level Monitoring Using Differential Pressure Sensors
The purpose of presented paper is to demonstrate an innovative approach for low cost continuous liquid level monitoring based on virtual instrumentation. Most of the traditional measuring systems were designed and implemented by complicated hardware circuitry. It made the product expensive, with low functionality and with limited precision. With virtual measurement technology, more of the instr...
متن کاملOtdr Distributed Sensing of Liquid Hydrocarbons Using Polymer-clad Optical Fibers
A distributed sensing system for apolar hydrocarbons is presented which is built from a chemically sensitive polymer-clad silica fiber adapted to an optical time domain reflectometer (OTDR) setup. OTDR measurements allow locating and detecting chemicals by measuring the time delay between short light pulses entering the fiber and discrete changes in the backscatter signals that are caused by lo...

In operation, the slab is inserte...
متن کاملDistributed Fibre Optic Sensors for the Detection of Liquid Spills
A range of distributed fibre optic sensors for the detection and location of aqueous, chemical and hydrocarbon fluid spills is presented. The sensors incorporate polymers that convert the swelling into a localised loss on an optical fibre when fluid exposure occurs. Optical Time Domain Reflectometry (OTDR) techniques are employed to rapidly detect and locate target liquids and chemicals at mult...
