Level Radar LCR20 Measuring principle Measuring principle The device is a "downward-looking" measuring system, which functions according to the time- offlight (ToF) method. It measures the distance from the reference point R to the product surface. Radar pulses are emitted by an antenna, reflected off the product surface and received again by the radar system.
• No buildup • Relative dielectric constant ε > 4 Contact Pepperl+Fuchs for lower ε values Usable measuring range The usable measuring range depends on the antenna size, the medium's reflective properties, the installation position and any possible interference reflections.
