243 Reservoir Water Level Detection Based on Optical Fiber Temperature Sensor Available to Purchase

The paper introduces a method of reservoir water level detection based on distributed optical fiber temperature sensor (DTS). First it introduces the working principle of DTS and the water-level determination principle by measuring the surface temperature of optical fiber. Then it gives different ways of laying optical fibers and gets the most cost-effective to meet the precision requirement. The result from engineering application shows that the positioning precision can reach to 10mm.
