Reliable Maximum and Minimum Liquid Level Monitoring
Liquid level monitoring relays detect conductive liquids through connected electrodes and use the measured resistance to determine the liquid level condition. The ABB CM-ENS.13P can be used in filling and draining systems to supervise minimum and maximum levels and provide an output signal for controlling pumps, valves or associated automation equipment.
Its adjustable 5–100 kΩ sensitivity allows the relay to be matched to different conductive fluids. This makes the CM-ENS.13P suitable for applications requiring automatic level control, overflow prevention, dry-running protection or signalling of monitored liquid level conditions.
Typical Applications
- Maximum and minimum liquid level monitoring.
- Automatic tank filling systems.
- Automatic draining and emptying systems.
- Pump dry-running protection.
- Tank and vessel overflow protection.
- Water and wastewater handling equipment.
- Industrial process tanks containing conductive liquids.
- Pump, valve and process control panels.
