Groundwater Level and Temperature Monitoring at Guangyuan Railway Station [Dayu Electronics]

　　1. Date: October 9, 2024

　　2. Location: Guangyuan City, Sichuan Province

　　3. Products Used: Telemetry Terminal RTU + Pressure Water Level Meter

　　Overview: This project involves groundwater level and temperature monitoring at Guangyuan Railway Station. A steel pipe well (well depth 25 meters, diameter 200mm) located at the midpoint of the Jialing River section 300 meters in front of the railway station is monitored in real time for groundwater level and temperature, enabling effective flood disaster prevention in advance. For real-time groundwater monitoring, the pressure water level sensor outputs via RS485, and the telemetry terminal RTU collects the data and transmits it wirelessly via 4G to the company's backend server. Relevant management personnel can log in via mobile phone or computer to view real-time monitoring data and historical data, and be reminded to promptly carry out corresponding work.

　　Product Selection: According to the site inspection and the owner's requirements, the products selected for this project are manufactured by Fuzhou Dayu Electronic Technology Co., Ltd.: The pressure water level meter is used for on-site front-end collection of water level and temperature; data is collected and transmitted via the telemetry terminal RTU.

　　Power Supply: After verification, there is no available power source on site, and the client is unwilling to add a solar power system. Therefore, a telemetry terminal RTU with a built-in lithium battery is selected (the built-in lithium battery can supply power for 1.5 to 2 years, and the pressure water level meter is powered by the RTU. When the battery runs out later, the owner can disassemble it for recharging).
