TR-155 : Development of data acquisition system (DAS) instrumentation

Abstract

The need for collection of reliable hydrological and meteorological data is obvious in flood and weather forecasting, and efficient water management. Recent advances in electronic technology have accelerated the development of data logging devices that are both compact and capable of monitoring many sensors. In order to improve the quality, quantity and/or timely receipt of the hydro-meteorological data, the semi-automated or automated data acquisition systems are preferred.

Such advanced instruments are now available in world market with various manufacturers. With the objective of developing capabilities for fabrication of indigenous automated data acquisition system, with state-of-art features, a training programme was organised under an Indo-Dutch collaborative project (WAMATRA II) at the Delft Hydraulics, The Netherlands. The present report has been prepared by Sri V C Goyal, Scientist of the Institute, and is part of the training which he received at the Delft Hydraulics, The Netherlands.
