Electric level gauge for measuring dynamic water level in wells

Abstract

Electrolevel gauge is designed to measure the dynamic water level in wells during pumping (Fig. 1). The maximum depth measured by the device is 100 m, measurement accuracy + 0.05%. The operating principle of the device is based on the closing of the electric circuit between the tip lowered into the well and water, determined by the deviation of the galvanometer arrow (Fig. 2). The depth at which the circuit is closed is determined by the length of the insulated wire lowered into the well (see article). In conclusion, it should be noted that the above described electric level gauge gives quite sufficient accuracy for practice in measuring both static and dynamic water levels in wells at single and cluster pumping.
