Krohne, which describes itself as “a global technology leader in the development, manufacture and distribution of accurate, reliable and cost effective measuring instruments for the process industries”, has introduced the new OPTIFLEX 1100 C level meter for liquids and solids in non-explosive environments. The OPTIFLEX 1100 C offers a “cost-effective and higher performing replacement for traditional level meters such as RF capacitance, conductive and pressure level meters.”

The OPTIFLEX 1100 C is two-wire, loop-powered and available with a standard 20 m cable or segmented coaxial probe for liquids and a 10 m cable probe for solids. All probes can be shortened on site and commissioning is completed via an intuitive 5-step “quick set-up” procedure. The OPTIFLEX 1100 C is available with an integrated display and keypad in the cover so that it is not necessary to open the housing cover for configuration. A blind version is also available. Multiple blind versions can be configured on site, using a single HMI (Human-Machine Interface) service tool.

The OPTIFLEX 1100 C uses TDR (Time Domain Reflectometry) technology. This state-of-the-art technology measures level independent from physical property variations such as dielectric constants, pressure or density. Unlike traditional meters, OPTIFLEX 1100 C does not need any wet calibration, is immune to linearity problems in irregular tank shapes and has neither fragile nor moving parts. The OPTIFLEX 1100 C is the latest addition to the popular OPTIFLEX product family next to the existing high-precision OPTIFLEX 1300 C TDR level meter, which is widely used in hazardous environments such as the mining industry.
