XH-M203 Automatic Water Level Controller Module

The XH-M203 Automatic Water Level Controller Module is a compact electronic control module designed to automate pump operation by monitoring and maintaining the liquid level in tanks, reservoirs, or similar systems. It provides reliable on/off control to help prevent pump dry-run and reduce overflow risk by responding to level input from appropriate external sensors or probes.Engineered for straightforward integration, the module is intended to be incorporated into new or existing water management setups where automated level control is required. Typical applications include household and light commercial water tanks, cisterns, and small-scale irrigation storage, where consistent level regulation improves system convenience and safety.Installation requires connecting the module to a compatible set of level sensing inputs and to the pump control circuit; it is designed for installers familiar with basic electrical wiring and pump control safety practices. The module operates as the control logic element, switching the pump circuit based on the sensed liquid level. Proper installation and correct selection of external sensors are essential for effective performance and long-term reliability.This module is intended for use in systems governed by local electrical codes and safe-practice guidelines and should be installed by qualified personnel when required by applicable regulations.
