6.4.7 Thresholds and parasitic signals
General notes
The low-power electromagnetic signal from the device goes down the probe. The surface of the
process and objects in the tank make reflections. These reflections go back up the probe to the
signal converter. The signal converter changes the reflections into voltage amplitudes.
Reflections from objects in the tanks are interference signals (parasitic signals).
How thresholds work
Thresholds let the device ignore reflections with small amplitudes and monitor changes in level.
2.5.7 MEAS. THRESH. (measurement threshold) sets the threshold for the signal after reflection
on the surface of the tank contents. This threshold is measured in thousandths (1...1000) of the
reference pulse amplitude (value= 1000). A threshold of 100 is equivalent to 10% of the amplitude
of the reference pulse at a distance of 1 m / 3.3 ft from the thread stop.
The user can do a check of the signal amplitude after reflection on the surface of the tank
contents. 2.5.6 MEAS. AMP. (measured pulse amplitude) is the signal amplitude (after reflection
on the surface of the tank contents) compared with the reference pulse amplitude. This value is
measured in thousandths (1...1000) of the reference pulse amplitude (value= 1000). Although this
data refers to any point along the device measuring range, the value shows the attenuation of the
signal amplitude at a distance of 1 m / 3.3 ft from the thread stop. This value helps you to set the
measurement threshold in menu item 2.5.7 MEAS. THRESH.
INFORMATION!
For more data on menu items, refer to Function description on page 38.
How to use thresholds
INFORMATION!
If there is a parasitic signal above the level and the threshold is too low, the device can
incorrectly use it as the level signal.

Parasitic signal. A signal from a level switch that is in the limits of the electromagnetic field around the probe.
Level signal of the tank contents
The level threshold is correct. The device ignores the parasitic signal and measures level correctly.
The level threshold is too low. The device can use the parasitic signal as the level signal.
If the parasitic signal is smaller than the correct level, you can manually change the
threshold to find the signal. This procedure tells you how to change the level threshold
to find the correct signal:
• Look at the menu item 2.5.6 MEAS. AMP.
i
Make a note of the amplitude of the correct level signal.
• Go to 2.5.7 MEAS. THRESH.
• Increase the amplitude of the level threshold.
i This value must be more than the incorrect signal. We recommend that you set the level
threshold at half the amplitude of the correct signal.
• Save the settings.
The threshold increases. It ignores the parasite signal and uses the first signal it finds.

This Guided Radar (TDR) level meter has been developed from a proven technology called Time
Domain Reflectometry (TDR).
The device transmits low-intensity electromagnetic pulses of approximately one nanosecond
width along a rigid or flexible conductor. These pulses move at the speed of light. When the
pulses reach the surface of the product to be measured, the pulses are reflected back to the
signal converter.
The device measures the time from when the pulse is transmitted to when it is received: half of
this time is equivalent to the distance from the reference point of the device to the surface of the
product. The time value is converted into an output current of 4...20 mA.
Dust, foam, vapour, agitated surfaces, boiling surfaces, changes in pressure, changes in
temperature, changes in dielectric constant and changes in density do not have an effect on
device performance.

9.2 Glossary
C
Cable
This is a wire rope. It is 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 εr, DK and relative permittivity. This gives the
strength of the measurement pulse reflected back to the device's signal
converter.
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
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.
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 and EN 61326-2-3 for further details.
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
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 for more details.
L
Level
This is a display option. It is the height from the bottom of the tank (userdefined) to the surface of the top product (Tank height – distance). Refer to
the diagrams at the end of this section.
M
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
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
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.
O
Operators
68
Users who can choose how to display measurements. They cannot
configure the device in supervisor mode.

APPENDIX 9
OPTIFLEX 1100 C
P
Probe
This is either a metallic cable or rod used to guide the measurement pulse
to the process.
Probe length
Ordered length of probe, L, from the thread stop 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.
S
Supervisors
Users who can configure the device in supervisor mode. They cannot
configure the device in service mode.
T
TDR
Time domain reflectometry (TDR). The principle used by the device to
measure level.
Top dead zone
The distance from the thread stop to the top limit of the measuring range.
Also refer to Measurement limits on page 64.
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.
U
Ullage mass
This is a display option. 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
This is a display option. It shows the unfilled volume. Refer to the diagrams
at the end of this section.
