Dielectric constant
Dielectric constant Dielectric constant
Dielectric constant An electrical property of the product to be measured used in Radar
measurement. Also known as
ε
r, DK and relative permittivity. Defines the
strength of the wave reflected back to the device's signal converter.
Distance
Distance Distance
Distance The distance from the matching element to the surface of the measured
product (measurement without a float) or the target on top of the float in
the bypass chamber. See the diagrams at the end of this section.
DTM DTM DTM DTM Device Type Manager. A driver for use in the PACTware
™
program. All data
and functions of the device are included in it.
Electromagnetic compatibility
Electromagnetic compatibility Electromagnetic compatibility
Electromagnetic compatibility Defines how much a device influences or is influenced by other devices that
generate electromagnetic fields during operation. Refer to European
standard EN 61326-1 for further details.
FMCW FMCW FMCW FMCW Frequency-modulated continuous-wave radar technology. The signal is
continuously present, but the frequency is modulated, usually in
successive linear ramps over time (frequency sweeps).

False radar reflections.
Level Level Level Level Height from the bottom of the tank (user-defined) to the surface of the top
product (Tank height
–
distance). See the diagrams at the end of this
section.
Matching element
Matching element Matching element
Matching element The part of the device that is welded to the top of the magnetic level
indicator. It is used for the controlled emission and collection of radar
signals.
Operators Operators Operators Operators Users who can choose how to display measurements. They cannot
configure the device in supervisor mode.
