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.
Direct mode

Direct mode
Direct mode
The instrument sends a signal along the probe. It receives the reflection of
the signal from the surface of the tank contents. The instrument uses an
algorithm to convert the time it takes to receive the signal into a distance.
This is for products with a dielectric constant >1.6 (this depends on the
probe type). Refer also TBF mode

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 free space and can potentially influence
the electromagnetic field around the probe. This can cause a measurement
error. Also refer to
General requirements
on page 28.

Distance
Distance
This is a display option. It is the distance from the face of flange 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.
