Innovative Floatless Technology

c-level sensor

The innovative C-Level™ sensor provides continuous level monitoring in tank applications.

The simple and accurate C-Level™ Sensor converts the water pressure in a tank into a low voltage electrical signal that is read by a variety of level monitoring products manufactured exclusively by SJE Rhombus. This innovative technology provides for continuous level monitoring for wastewater tank applications, confined space applications and systems with a high grease content.

C-Level™ Sensor is available for these Level Monitoring Products:
