　　 Electronic water level gauge As an essential tool for measuring water levels, before the advent of electronic water-level gauges, people typically used bamboo poles to assess water height or relied on water‑level cups to gauge river levels. With the rapid advancement of science and technology, electronic water-level gauges have become a primary device for automated water-level measurement and monitoring. Serving as digital sensors, they collect water-level data by leveraging the principle of water’s slight electrical conductivity, while employing high‑performance processor chips as controllers. Data are then acquired via electrical probes, subjected to digital encoding, scaling, sampling, and digital processing, and transmitted—either through wired or wireless communication—to software applications or central monitoring stations, enabling real-time water-level monitoring and early warning. Next, we will discuss the three distinct operating modes of electronic water-level gauges, along with installation procedures and key considerations during installation.

　　Electronic water level gauges operate in three distinct modes: empty‑height mode, submerged‑water mode, and tilt‑angle mode. In empty‑height mode, the water level reading is calculated as the gauge’s total length minus the water level plus a reference value. In submerged‑water mode, the reading equals the water level plus the reference value. In tilt‑angle mode, the reading is obtained by multiplying the water level by the corresponding angle and then adding the reference value. The gauge’s internal components are made from highly sealed materials and undergo special treatment to maintain a hermetic seal, protecting the device from corrosive liquids, sludge, contaminants, sediments, and other impurities. As a result, it is well suited for monitoring water levels in reservoirs, lakes, rivers, hydropower stations, irrigation projects, as well as in municipal water supply and urban wastewater treatment systems.

　　The electronic water level gauge can be installed vertically. Depending on the specific site conditions, sensor segments of different specifications can be combined to achieve the desired length, and then connected into a single integrated sensor using U‑shaped connectors. Alternatively, it can be mounted at an angle against a wall; this method is similar to the vertical installation described earlier. In this case, the measurement length must be converted to account for the inclined mounting, which improves accuracy because the measurement is taken along the height.

　　 Electronic water level gauge During installation, arrange the sensor segments in sequence according to the specified mounting length requirements, ensuring that the sensors are oriented correctly. When the total connection length exceeds 4 meters, install the system in sections on-site, proceeding step by step. Without additional support measures, it is not recommended to assemble the entire cascade before installation, to avoid damage during handling and transportation. In all application environments, the electronic water level gauge maintains a measurement accuracy of 1 cm, regardless of length; its stainless steel housing provides robust protection and strong resistance to electromagnetic interference.
