10. Glossary
B
Blocking distance
A minimum distance from the device signal converter where it is impossible to for the gauge to measure.
Dependant on probe type. Refer to section 7.1.2: Technical data; blocking distance for further information.
C
Cable
Wire rope. Used as a measurement pulse guide.
D
Dielectric constant
An electrical property of the product to be measured used in TDR measurement. Also known as
ε
r
, DK and
relative permittivity. Defines the strength of the measurement pulse reflected back to the device's signal
converter.
Discontinuities
Objects or parts of objects (including the tank) that are in the tank, are possibly in the probe's free space
and can potentially influence the electromagnetic field around the probe. This can cause a measurement
error. See also section 1.2.1 Location: all applications.
Distance
Distance from the face of flange to the level (1 product) or the surface of the top product (2 or more
products). See diagram below.
Distance mass
For displaying "empty" mass or mass of the product that can be put into the tank. See diagram below.
Distance volume
Unfilled or ullage volume. See diagram below.
E
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 A1+A2 for further details.
Electromagnetic field
Zone generated by the device around the probe while switched on. Influenced to a certain degree by nearby
metallic objects. See also section 1.2.1 Location: all applications.
