3System Description
3.1 Overview
The level measuring device LB 470RID is an industrial measuring system for the
contactless and continuous determination of the level of a product in a container.
The LB 470RID measuring system extends the functionality of the radiometric level
measurement of the LB 470 by the function of Radiation Interference Discrimina-
tion (RID).
A complete measuring system consists of the following components:
•Evaluation unit DuoXpert LB 470RID
•Source
•Shields
•Point detector / rod detector(s)
These instructions concern the operation of the evaluation unit DuoXpert
LB 470RID (Fig. 1, item 6). The operation of other system components is part of the
independent instructions of the respective system components. The EVUs are stand-
ard equipment in switch rooms with 19" subracks or switchboards.
Depending on the measuring task and the composition of the measuring product
and containers, different arrangements and system components are required, see
3.5 Measurement Arrangements.

3.2 Measuring Principle
Gamma radiation is used to penetrate a medium in a container. The attenuation
of the radiation is analyzed to measure the level in the container.
The evaluation DuoXpert LB 470RID (master EVU) is used for the evaluation, trans-
mission and visualization of measured values which it receives from the connected
detectors.
The EVU is an independent measurement channel. If several measurement chan-
nels are required, an independent EVU must be used for each channel.
For covering larger measuring ranges with level measurements, it is possible to
connect multiple detectors on a level measuring device LB 470. To do this, an addi-
tional slave module is required (optional) for each additional detector after the
first. A maximum of 16 slave modules can be connected per master EVU. A cascaded
measurement system with a maximum of 17 detectors can be set up in this way.
Tip
Further information on the functional principle of the detectors can be found
in the operating manual of the detector.
3.3 Radiation Interference
Radiometric continuous Level Measurements and Interference
Radiation
The highly sensitive large volume gamma-ray detectors used in continuous level
measurements are susceptible to the effects of strong radiation external to the
level measurement system. Problems can occur when very powerful radioactive
sources, (typically used in the testing of welds and other material properties in the
construction or refurbishment of pipes), are in use in the vicinity of the level meas-
urement system.
These strong and sporadic radiation fields are detected and counted by the level
system in addition to the valid counts resulting from the source used to determine
the level in the vessel. Without additional precautions, the evaluation unit would
add the unwanted counts to the wanted counts and provide an incorrectly low
reading for the level in the measured vessel. This type of process error can be ex-
pensive and even dangerous.
he standard LB 470 evaluation unit is configured to deal with the effects of spo-
radic unwanted radiation by recognizing a fast increase of input count rate due to
unwanted radiation and freezing the signal representing fluid level in the vessel at
the last correct value for the duration of the interference, then reverting to a nor-
mal measurement mode when the unwanted radiation stops. During this time, no
information about the actual fill level is available and the process has to be con-
trolled manually. This is satisfactory for situations where level changes are
relatively slow or interference takes place infrequently. However, in processes
where the level in the vessel fluctuates quickly and interfering radioactive sources
are in use at the site, automated safety features are required to avoid errors due
to interfering radiation.
Suppression of Unwanted Radiation Signals
A patented LB 440-RID1continuous level system is now available which almost com-
pletely eliminates the effects of interference radiation on the accuracy of level

measurements. This system distinguishes between the energies of the wanted and
unwanted radioactive isotopes and suppresses the effects of the unwanted radia-
tion. This represents a huge advantage in situations where frequent weld testing
is performed.
3.3.1 Scintillation Detectors
Every gamma absorbed in the scintillator material generates a light flash whose
intensity depends on the energy of the gamma radiation. The light pulses are con-
verted in the coupled photomultiplier into voltage pulses whose height is
proportional to the energy of the gamma which generated it.
The detector electronics compares the height of the measured voltage pulse to a
preset voltage, the measuring threshold. Only pulses of sufficient voltage (height)
to exceed the measuring threshold are counted by the evaluation electronics and
determine the measured pulse rate in the measuring channel (MC) and the level in
the container is calculated from the pulse rate in the measuring channel. To be
able to work with as low as possible radioactive source activities, the measuring
threshold is set so low that all radiation pulses are registered, and high enough
that the noise of the electronics cannot contribute to the measured pulse rate. The
height of the measuring threshold is a direct measure of the sensitivity of the meas-
uring system: The higher the measuring threshold, the higher is the source activity
required to reach the same count rate.

56925-1BA2 Rev.02, 05/2021
3.3.2 Interference Radiation and Pulse Height Analysis
Ionizing radiation registered by the detector which does not come from the meas-
uring source is called interference radiation. In the testing of welds and other
material testing, radioactive sources of very high activity (up to 100 Ci) are used.
These applications almost always use low energy radiation sources for example, Ir-
192 or Se-75. In contrast, the Nuclides used in the level measurements, in particular
Co-60, are high energetic radiation sources, with much lower activity.
An analysis of the voltage pulses (pulse amplitude or "height") registered by the
detector permits a differentiation between interference radiation and measuring
radiation since the pulse height is dependent on the energy of the isotope. The
pulse height spectrum in illustration 3 shows the distribution of the pulse heights
generated by gamma radiation from Co-60 or Ir-192 sources in a rod detector with
plastic scintillator. On account of the high radiation energy, the spectrum of Co-60
includes big pulse heights, as opposed to pulse heights for an Ir-192 source. In the
pulse height spectrum from illustration 3, practically no Ir-192 pulses lie above a
height of 700 mV. The energy of Se-75 is below Ir-192 and generates even lower
pulse heights.
Fig
. 2 Pulse Height Spectrum
All pulses above the measuring threshold contribute to the count rate in the meas-
uring channel. When Ir-192 interference radiation influence is present, all Ir-192
pulses are also counted. This causes the level measurement in the vessel to read too
low.
