OPTIFLEX 1100 C – Version with single cable

Guided radar (TDR) level transmitter OPTIFLEX 1100 C – Version with single cable

The OPTIFLEX 1100 is a guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for basic storage applications in non-hazardous areas. The level transmitter is a higher performing replacement for traditional level transmitters such as RF capacitance or conductive level transmitters.

Product highlights
