Cable Cable Cable Cable This is a wire rope. It is used as a measurement pulse guide.
Dielectric constant Dielectric constant Dielectric constant Dielectric constant An electrical property of the product to be measured used in TDR
measurement. Also known as ε
r
, DK and relative permittivity. This gives the
strength of the measurement pulse reflected back to the device's signal
converter.
Discontinuities Discontinuities Discontinuities Discontinuities These are objects or parts of objects (including the tank) that are in the
tank, are possibly in the probe's empty space and can potentially influence
the electromagnetic field around the probe. This can cause a measurement
error.
Distance Distance Distance Distance This is a display option. It is the distance from the thread stop to the level (1
product) or the surface of the top product (2 or more products). Refer to
the diagrams at the end of this section.
Electromagnetic compatibility Electromagnetic compatibility Electromagnetic compatibility Electromagnetic compatibility Defines how much a device influences or is influenced by other devices that
generate electromagnetic fields during operation. Refer to European
standard EN 61326-1 and EN 61326-2-3 for further details.
Electromagnetic field Electromagnetic field Electromagnetic field Electromagnetic field This is a physical field that is produced by electrically-charged objects and
which may affect the behaviour of other objects near to the field.
Empty space Empty space Empty space Empty space A minimum diameter around a probe that should have no objects in it for
the device to work correctly. This depends on the probe type. Refer to
Installation

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.
Measuring length Measuring length Measuring length Measuring length Length, L', of from the thread stop 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.
Operators Operators Operators Operators Users who can choose how to display measurements. They cannot
configure the device in supervisor mode.
