Description
The KROHNE OPTIFLEX 1100 C is a cost-effective two-wire guided radar (TDR) level transmitter for liquids, pastes, powders and granulates in non-hazardous areas. It measures liquids up to 20 m and solids up to 10 m with ±10 mm accuracy, needs no calibration (only the probe length and a 5-step set-up) and can show volume using a 30-point strapping table.
It works at −50 to +100 °C and up to 16 barg with stainless steel probes and process connections (G or NPT ¾–1 in). It gives a loop-powered 4–20 mA output from a 14–30 V DC supply and has an IP66/67 aluminium housing with an LCD in nine languages.
Argonmark Ltd supplies KROHNE instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
