Guided radar level measurement

Our product finder helps you to search for suitable measuring devices, software or system components via product characteristics. Applicator leads you through an individual product selection via application parameters.

Guided radar level measurement is well suited to liquids and bulk solids. The surface condition of the medium is of minor importance due to the safe guidance of the reflected waves. Turbulent liquid surfaces or foam formation as well as different angled surfaces or outflow funnels, as the occur in bulk solids, do not influence the measurement. Guided radar is also the first choice for interface measurement.

Measuring Principle Guided Radar with Time-of-Flight

Guided radar measurement: Measuring Principle

Levelflex works with high-frequency radar pulses which are emitted and guided along the probe. As the pulse meets the medium surface, part of the emitted pulse is reflected due to a change of the dc value (relative dielectric constant). The Time-of-Flight between pulse launching and receiving is measured and analyzed by the instrument and constitutes a direct measure for the distance between the process connection and the product surface.

Benefits

  • Reliable measurement: Unaffected by medium surfaces and tank obstacles or baffles

  • Additional measuring safety through End-of-Probe (EoP) evaluation

  • Safe measurement also during filling
