Layer Layer Layer Layer This is a display option. It gives the thickness of top product. The layer must
be more than 50 mm or 2¨ for accurate measurement of level and/or
interface. Refer to the diagrams at the end of this section.
Level Level Level Level This is a display option. It is the height from the bottom of the tank (user-
defined) to the surface of the top product (Tank height – distance). Refer to
the diagrams at the end of this section.
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.
Sensor length Sensor length Sensor length Sensor length Length, L', of from the face of the flange to end of the guide. If you ordered
a cable probe, this does not include the counterweight. Refer to the
diagram 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 127.
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, the
interface and the probe end. Also refer to
Thresholds and parasitic signals
on page 92.
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 141.
