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 silo (user-defined) to the surface of the top
product (Tank height – distance). See the diagrams at the end of this
section.
Total mass of silo 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 silo 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 silo contents.
