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.

OPTIFLEX 8200

Guided radar (TDR) level transmitter for liquids at high temperature and pressure

  • Continuous level and interface measurement in boilers, reactors and separators
  • With dynamic gas-phase compensation for boiler applications
  • Measuring range: 0.6…40 m; 2…131 ft
  • -50…+315°C; -58…+599°F; -1…320 barg; -14.5…4641 psig

The OPTIFLEX 8200 is a 2-wire guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for level and interface measurement under extreme conditions in the power, oil and gas industries. Using an algorithm called “Dynamic Gas-phase Compensation (GDC)”, the device measures accurately and without increased blocking distance the level of products in processes where the composition of the gas above the product can change suddenly (e.g. in steam boilers).

For high safety requirements in applications with dangerous media, the OPTIFLEX 8200 features a single or double ceramic process seal system. 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.
