C350 Non-Contact High & Low Liquid Level Controller with Two Detection Heads — Automatic Fill/Drain

The C350 controller paired with two liquid level detection heads provides automatic high/low level management for a container. Using non-contact intelligent sensors, the system monitors both low and high thresholds and controls pumping in a repeating cycle. When the low-level detector senses the liquid has fallen below the set point, it issues a low-level alarm signal that triggers the C350 to close its relay and start the water pump to raise the level. Once the liquid reaches the preset high point, the high-level detector sends a signal to the C350 to open the relay, automatically stopping the pump. This cycle keeps the container’s liquid level stable through automatic filling and drainage control. 1P is a probe whose role is to maintain a specific water level.
