Guided Radar (TDR) Level Meter

OPTIFLEX 1300 C Guided Radar (TDR) Level Meter
  • Universal device that can measure level of liquids, pastes, granulates, powders, and liquid interface
  • Easy to install: onsite calibration is not needed
  • Operates up to 300 bar / 4350 psi

This device is a Guided Radar (TDR) Level Meter for measuring distance, level, interface, level and interface, volume and mass. It has higher signal dynamics and a sharper pulse than conventional TDR devices and therefore better reproducibility and accuracy.

A variant with a remote converter can be mounted up to 14.5 m / 47.6 ft from the probe. The device can operate at very low and very high process temperatures as long as the process connection temperature limits are observed.
