I. Overview

The WDC type electrode-type electronic water level gauge is a new generation of digital sensor. It utilizes the principle of the slight conductivity of water to measure the water level by the electrode and obtain data. Its unique advantage is that the error is not affected by environmental factors; it only depends on the electrode spacing, offering high measurement accuracy, stability, and reliability. It is easy to use and avoids the shortcomings of traditional water level sensors, such as zero drift, temperature drift, and being affected by water quality and weeds. The signal can be transmitted through various transmission methods.

This product can continuously and automatically monitor water levels over a long period, with relaxed environmental requirements. It features low installation costs, high stability, and precision. It is applicable in urban flooding, reservoirs, lakes, rivers, irrigation areas, and more.

II. Key Features
