A Differential Level Controller is an electronic instrument used to measure and control the level difference between two points (high side and low side) in tanks, vessels, sumps, filters, and process equipment. It receives signals from differential pressure transmitters or level sensors and provides monitoring, display, alarms, and control outputs for maintaining the desired differential level.
