Non-Contact Intelligent High & Low Liquid Level Controller with Two Detection Heads — C350 Relay Auto Fill/Drain, 1P Probe

This system uses a high/low level controller paired with two liquid level detection heads to manage tank liquid levels automatically. When the liquid falls below the set low point, the low-level sensor issues a low liquid level alarm signal to the C350 controller. The C350 then closes its relay to start the water pump and begin filling. Once the liquid reaches the preset high point, the high-level sensor sends a signal to the C350, which opens the relay and automatically stops the pump, completing the fill/drain cycle. The arrangement provides continuous, cyclical automatic control of the container’s liquid level and keeps the tank level stable. Included is a 1P probe whose purpose is to maintain the specified water level.
