An area with a potentially explosive atmosphere. Trained personnel can
install and use a device in this area. The device must be ordered with the
appropriate options. The device requires approvals (ATEX, IECEx, cQPSus,
NEPSI etc.) related to site specifications. You can find more data about
hazardous areas in the Ex Manuals and Ex Certificates of Compliance.
A common antenna for most applications. It is used for the controlled
emission and collection of radar signals.
False radar reflections usually caused by equipment in the tank.
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.
Total mass of tank contents.
Software that operates and configures field devices from a remote
workstation. It is not necessary to use fieldbus software or programs
developed by the manufacturer.
Signal reflected from the surface of the tank contents.
A set of electronic components in the device that send the measurement
signal through some signal filters. They identify and measure the level of
the tank contents.
Tank Bottom Following (TBF) mode is an alternative measurement mode. It
allows the device to measure tank contents with very low dielectric
constants. TBF mode uses the reflection of the tank bottom to indirectly
measure the level of the tank contents.
Unfilled volume. See the diagrams at the end of this section.
