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.
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.
