Assessing the accuracy of TDR-based water leak detection system

open access: yesResults in Physics, 2018
The use of TDR system to detect leakage locations in underground pipes has been developed in recent years. In this system, a bi-wire is installed in parallel with the underground pipes and is considered as a TDR sensor.

Robust Filtering for TDR Traces [PDF]

open access: yesIEEE Transactions on Instrumentation and Measurement, 2008
Time-domain reflectometry (TDR) is a valuable technique for the measurement of dielectric properties of soils. The filtering of noisy TDR traces is treated in this paper. The problem of biased estimation occurs when the permittivity of the soil varies with the depth.
