Mass Mass Mass Mass This is a display option. It shows the total mass of tank contents. Use a
mass table or a volume table to display measurement data with mass
units.
Measurement pulse Measurement pulse Measurement pulse Measurement pulse The device transmits a short, low-powered electrical pulse or wave
transmitted down a guide to the process. The process (or the probe end if
in TBF measurement mode) reflects the pulse back to the device.
Operators Operators Operators Operators Users who can choose how to display measurements. They cannot
configure the device in supervisor mode.
Probe Probe Probe Probe This is either a metallic cable or rod used to guide the measurement pulse
to the process.
Probe length Probe length Probe length Probe length Ordered length of probe, L, from the face of the flange to end of the guide. If
you ordered a cable probe, this includes the counterweight. Refer to the
diagrams at the end of this section.
Supervisors Supervisors Supervisors Supervisors Users who can configure the device in supervisor mode. They cannot
configure the device in service mode.
TBF mode TBF mode TBF mode TBF mode Tank Bottom Following (TBF) mode. If the product has a low dielectric
constant, use this mode. TBF mode uses the end of the probe to indirectly
measure the tank contents.
TDR TDR TDR TDR Time domain reflectometry (TDR). The principle used by the device to
measure level. For more data, refer to
Measuring principle on page 115.
Threshold Threshold Threshold Threshold A number of limits set either manually or automatically by the signal
converter to identify the reflected measurement pulses from the level, and
the probe end. For configuration data, refer to
Function description on page
74.
Top dead zone Top dead zone Top dead zone Top dead zone The distance from the flange to the top limit of the measuring range. Also
refer to
Measurement limits on page 125.
Ullage mass Ullage mass Ullage mass Ullage mass This is a display option. It shows empty mass or mass of the product that
can be put into the tank. Refer to the diagrams at the end of this section.
Ullage volume Ullage volume Ullage volume Ullage volume This is a display option. It shows the unfilled volume. Refer to the diagrams
at the end of this section.
Volume Volume Volume Volume Total volume of tank contents. Calculated with a volume table.
