About this ebook
A rugged, self-calibrating, time-domain reflectometer (TDR) device for monitoring groundwater elevations in piezometers was developed and demonstrated. The primary advantage of the TDR device over conventional downhole transducer technology is that the electronics are fixed at the surface where they are accessible and easy to maintain. The TDR instrumentation is also simple to install and does not require field calibration.
