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 and interface. For more data, refer to
Measuring principle
on page 144.
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
Thresholds and interference
signals
on page 109.
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 160.
Ullage mass Ullage mass Ullage mass Ullage mass This is a display option (parameter name: distance conversion). 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 (parameter name: distance conversion). 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.
