C-Level™ Sensor

Innovative Floatless Technology

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 Features:

  • Operates on low voltage
  • Compact, non-moving design
  • One sensor replaces up to four floats
  • Easy to install
  • Available in cable lengths up to 300 ft. (91.44 m)
  • Excellent alternative to mercury floats

C-Level Sensor Models

  • CL40 - sensing range up to 40 inches (101.6 cm) for smaller tank applications
  • CL100 - sensing range up to 100 inches (254 cm) for larger tank applications

US Patent No. 8,567,242; 8,336,385; 8,650,949.
