RBDM handheld ultrasonic water depth meters is used in reservoir, lakes, rivers or shallow sea etc. The main principal is to place ultrasonic transducer above the water or in the water and use ultrasonic spreading in the water to get the calculated water depth by instrument. This instrument applied international advanced technology, equipped also with complete water depth measurement function, control function, signal transfer function and man-machine communication function. This instrument is a water depth measurement instrument of a combination of ultrasonic receive and dispatch sensor, servo circuit, temperature compensation sensor an compensation circuit unit, display, control signal output and serial signal or analog quantity output unit(choice). Its main advantages are high reliability, long life, easy access, simple application, precise measurement and less maintenance, it has already been widely used in hydrographic survey, hydraulic power plant, reservoir area, shallow sea, lakes and river course survey, environment water area survey etc.
