Walfront Water Detectors & Alarms Editorial Review

The XH-M203 Full Automatic Water Level Controller is a reliable solution for water Conservancy projects. It features a liquid level detection sensor module with a relay output of ACDC 12V. The product is easy to install and comes with a simple diagram that is easy to understand. The sensors required for the system are the 2pin level sensors. The input voltage range is 12V DC. However, the product lacks a decent manual and upon receiving the product, the instruction was only in Chinese, which might be a significant concern for those who do not speak or read Chinese. However, the product worked well with the help of the diagram, and the only issue was with the incorrect wire colors, which users need to double-check. Overall, this is a reliable water level controller for water Conservancy projects.
