KROHNE OPTIFLEXKROHNE Inc.’s OPTIFLEX 1100 C level meter for liquids and solids in non-explosive environments offers a higher performing replacement for traditional level meters such as RF capacitance, conductive, and pressure level meters. The meter 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 five-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 meter uses TDR (Time Domain Reflectometry) technology, which measures level independent from physical property variations such as dielectric constants, pressure or density. Unlike traditional meters, this meter does not need any wet calibration, is immune to linearity problems in irregular tank shapes, and has neither fragile nor moving parts. –
