Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use.

Application Examples

Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the:

Monitoring and control of liquid levels
Protection of pumps against dry running
Ability to detect liquid leaks in a system
Control of media mixing ratios
Control of liquid levels
