Measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the
mounting location, and eventual interference reflections.
The following tables describe the groups of media as well as the achievable measuring range as a
function of application and media group. If the dielectric constant of a medium is unknown, it is
recommended to assume media group B to ensure a reliable measurement.
