TDR level meter

for liquids and solids

Krohne Messtechnik GmbH

Krohne introduces the Optiflex 1100 C TDR guided radar level meter for liquids and solids in non-explosive environments. The device 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 2-wire, loop-powered and available with a standard 20m cable or segmented coaxial probe for liquids and a 10m cable probe for solids. All probes can be shortened on site and commissioning is completed via an intuitive 5-step ”Quick Setup” procedure. The meter 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 level meter uses TDR (Time Domain Reflectometry) technology. This technology measures level independent from physical property variations such as dielectric constants, pressure or density. Unlike traditional meters, it does not need any wet calibration, is immune to linearity problems in irregular tank shapes and has neither fragile nor moving parts.
