Continuous level measurement in liquids and solids with guided wave radar sensors

​

Guided radar level measurement with top-down installation of a Levelflex sensor offers perfect application fit in all industries. Guided radar with simple commissioning, trouble-free operation saves time and money. For usage in a wide range of applications - be it in simple storage tanks, in corrosive or aggressive media or heavy-duty applications.

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 they 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 that are emitted and guided along with 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
