17-Fabrication, Testing and Evaluation of Bellary type water level recorder.

Abstract

Automatic water level recorders are essential in the soil and water conservation and hydrological research. There is an urgent need to design and fabricate indigenous recorders, eliminating some of the constraints of the imported ones, such as the necessity of daily resetting the chart/stylus pen, frequent slips of the beaded wire, clogging and twisting of stylus pen etc., so as to record the runoff events accurately, instead of depending on the costly and imported water level recorders, involving considerable foreign exchange and time. To achieve this object, efforts made at the CS and WCR and TI, Research Centre, Bellary, have resulted in the development of a recorder and is found to work satisfactorily.
