Abstract

A fiber optic quasi-distributed sensing technique was suggested to use for detecting the location and severity of water leakage. A novel fiber optic sensor probe was devised with a vessel of water absorption material called as water combination soil (WCS) located between two highly reflected connectors. The largest vessel probe provides the highest sensitivity, 0.267 dB/ml, while the small one shows relatively low sensitivity, 0.067 dB/ml, and unstable response. The sensor probe with a high output value provides a high sensitivity with various detection levels while the number of total installable sensor probes decreases.
