Description
Overview
GAOTek sounder depth level sensor is a sounding instrument for measuring reservoirs, lakes, rivers, shallow water, and other water. When sounding, the ultrasonic transducer is placed on the water surface or at a certain position in the water. The current water depth can be automatically calculated by using the ultrasonic propagation principle in the water. The instrument adopts internationally advanced technology and has perfect functions for bathymetric survey, control, data transmission, and man-machine communication. It is a bathymetric instrument that integrates an ultrasonic transceiver sensor, servo circuit, temperature compensation sensor and compensation circuit unit, display, control signal output, and serial data or analog output unit(optional). It has the characteristics of less maintenance, high reliability, long life, easy to use, simple operation, and accurate measurement, so it is widely used in hydrological survey, hydropower plant, reservoir area, shallow sea, lake, river channel survey and environmental water area monitoring.
