C350 Non-Contact Intelligent High & Low Liquid Level Controller with Automatic Fill/Drain Sensors

This system combines a C350 controller with two non-contact liquid level detection heads (high and low) to provide automatic water fill and drain control. If the low-level sensor detects the liquid falling below the set point, it sends an alarm signal that causes the C350 to close its relay and start the pump to refill. When the liquid reaches the high-level sensor, that sensor signals the C350 to open the relay and stop the pump. The unit cycles automatically to keep the tank level stable. A 1P probe is included to help maintain the target water level.
