UTGWDH Handheld Ultrasonic Depth GaugeDetailed product description：

Product Overview
The UTGWDH handheld ultrasonic depth meter is a portable depth gauge used to measure water bodies such as reservoirs, lakes, rivers, and shallow seas. During depth measurement, the ultrasonic transducer is placed on the water surface or at a certain position, and the instrument automatically converts the water depth H using the fixed sound velocity VC of ultrasonic waves in water and the time T from ultrasonic transmission to reception. This product is developed by our company based on years of production experience and the advantages of various similar products, and is convenient and applicable for handheld ultrasonic distance measurement. The ultrasonic transceiver conversion circuit adopts a dedicated large-scale integrated circuit with a component placement rate of 99%, and displays the depth measurement results on a liquid crystal display, ensuring the long-term reliability of the product while reducing its power consumption to extremely low. Optional signal output compensates for the lack of output in traditional handheld products. It has the advantages of precise measurement, low power consumption, high reliability, easy use, simple operation, accurate measurement speed, and convenient portability. The instrument can measure depth in still water or in water with a certain velocity; The water flow velocity can reach about 5m/s, making it an ideal depth measurement instrument for hydrological surveys, hydropower plants, reservoir areas, lakes, river surveys, and environmental water monitoring.
