【 Model FT-CS120+】 Fengtu Technology: a professional manufacturer, dedicated team, and fast response, creating a reliable support in one. Handheld ultrasonic depth sounder builds a reliable system with high precision and long lifespan from chip to screen. The core ultrasonic transceiver conversion circuit adopts a dedicated large-scale integrated circuit. This design integrates numerous complex functions into a single chip, reduces the connection lines between components, lowers signal transmission loss and interference, and lays the foundation for high-precision measurement. At the same time, the high component placement rate ensures the stability and consistency of the circuit, effectively avoiding performance degradation caused by component virtual soldering and extending the service life of the equipment.

In terms of display, a LCD screen is used to present the depth measurement results. LCD display technology is mature, capable of displaying data clearly and accurately, and has low power consumption. Combined with highly integrated circuits, the overall power consumption of the machine is further reduced to an extremely low level. Low power consumption not only reduces energy consumption and usage costs, but also avoids heat accumulation caused by long-term high load operation, prevents component performance degradation due to overheating, and ensures high-precision measurement and long-term reliable operation of handheld ultrasonic depth sounders.

1、 Product Introduction

Ultrasonic depth sounder is a portable depth sounder used to measure water bodies such as reservoirs, lakes, rivers, and shallow seas. During depth measurement, the ultrasonic transducer is placed at a certain position below the water surface, 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 a convenient and applicable handheld ultrasonic distance measuring instrument developed by our company based on years of production experience and the advantages of various similar products. 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. 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 is ≤ 5m/s, making it an ideal depth measurement instrument for hydrological surveys, hydropower plant storage areas, lake and river surveys, and environmental water monitoring.
