The OPTIFLEX 7200 is a 2-wire guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. With its large choice of probe types and materials, the level transmitter is the high-end guided radar for level and interface measurement in the chemical or oil and gas industries. It is suitable for storage or process tanks up to 60 m / 196.85 ft, containing all kind of liquids – from hydrocarbons like slop oil or benzene to solvents and acids to cooling water or condensate.

The OPTIFLEX 7200 can be used at extended temperature and pressure conditions. It also has a patented “Dynamic Gas-phase Compensation (DGC)” mode that allows it to measure accurately and without increased blocking distance in processes where the composition of the gas above the liquid can change rapidly. Various converter and electronic versions like a remote converter or a sensor extension facilitate the access to the device. The level transmitter has approvals for use in hazardous areas.
