TLPR (Tank Level Probing Radar) devices only
Use approved personnel to install the device. The device and the tank agree with the RED (Radio
Equipment Directive) if you obey the instructions that follow:
• TLPR (Tank Level Probing Radar) are required to be installed at a permanent fixed position at
a closed (not open) metallic tank or reinforced concrete tank, or similar enclosure structure
made of comparable attenuating material;
• flanges and attachments of the TLPR equipment shall provide the necessary microwave
sealing by design;
• sight glasses shall be coated with a microwave-proof coating when necessary (i.e. electrically
conductive coating);
• manholes or connection flanges at the tank shall be closed to ensure a low-level leakage of
the signal into the air outside the tank;
• whenever possible, mounting of the TLPR equipment shall be on top of the tank structure
with the orientation of the antenna to point in a downward direction;
• installation and maintenance of the TLPR equipment shall be performed by professionally
trained individuals only.
For data about how to install EMI/RFI shielding gaskets, refer to the instructions supplied with
this accessory.

SAFETY INSTRUCTIONS
LPR (Level Probing Radar) devices only
Use approved personnel to install the device. If the device is operated in the open air (outdoors),
it agrees with the RED (Radio Equipment Directive) if you obey these instructions:
• The antenna must always point downwards. The boresight direction of the antenna must be
vertical. No other angles are permitted.
• Install the device more than 4 km / 2.485 mi away from radio astronomy sites.
• If the device is 4...40 km / 2.485...24.855 mi away from radio astronomy sites, do not install the
device more than 15 m / 49.21 ft above the ground.
CAUTION!
If it is necessary to install the device less than 4 km / 2.485 mi from radio astronomy sites, you
must get the approval of the national regulatory authority before installation (e.g. ANFR
(France), Bundesnetzagentur (Germany), Ofcom (United Kingdom) etc.).

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference which may cause un-
desired operation.
Changes or modifications made to this equipment not expressly approved by the manufacturer
may void the FCC authorizations to operate this equipment.

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•
Consult the dealer or an experienced radio/TV technician for help.

’
s instructions.
2. The use of this device is on a "no-interference, no-protection" basis. That is, the user shall ac-
cept operations of high-powered radar in the same frequency band which may interfere with or
damage this device. However, devices found to interfere with primary licensing operations will
be required to be removed at the user
’
s expense.
3. The TLPR device shall be installed and operated in a completely enclosed container to prevent
RF emissions, which can otherwise interfere with aeronautical navigation.
4. LPR devices: Ensure a vertically downward orientation of the transmit antenna and an instal-
lation only at fixed locations.

Astrophysical Observatory (DRAO) near Penticton, British Columbia. The coordinates of the
DRAO are latitude 49
°
19'15" N and longitude 119°37'12" W. For devices not meeting this 10 km
separation (e.g. those in the Okanagan Valley, British Columbia) the installer / user must coordinate with, and obtain the written concurrence of, the Director of the DRAO before the equipment can be installed or operated. The Director of the DRAO may be contacted at 250-497-2300
(tel.) or 250-497-2355 (fax). Alternatively, the Manager, Regulatory Standards, Industry Canada,
may be contacted.

DEVICE DESCRIPTION
2.2 Device description
This device is a 24 GHz FMCW-radar level transmitter. It is a non-contact technology and is 2wire loop-powered. It is designed to measure the distance, level, mass, volume and reflectivity of
granulates and powders. For more data about the measuring principle, refer to
principle
Radar level transmitters use an antenna to emit a signal to the surface of the measured product.
The device has many antennas available. Thus, it can measure most products even in difficult
conditions. Also refer to
If the device is ordered with the applicable options, it can be certified for use in hazardous areas.
The signal converter is attached directly to the process connection and the antenna. The
illustration that follows shows the types of antenna.

3.5 Pressure and temperature ranges
WARNING!
The process connection temperature range must agree with the temperature limits of the
gasket material. The operating pressure range is subject to the process connection used and the
flange temperature.

3.7.1 General notes
LPR and TLPR devices
WARNING!
LPR (Level Probing Radar)
LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic
LPR (Level Probing Radar)LPR (Level Probing Radar)
tank etc.). TLPR (Tank Level Probing Radar)
can use LPR devices for TLPR applications. For more data, refer to Radio approvals on page 11
Causes of interference signals
• Objects in the tank or silo.
• Sharp corners that are perpendicular to the path of the radar beam.
• Sudden changes in tank diameter in the path of the radar beam.
CAUTION!
Do not install the device above objects in the silo (ladder, supports etc.) or pit. Objects in the silo
or pit can cause interference signals. If there are interference signals, the device will not
measure correctly.
If it is not possible to install the device on another part of the silo or pit, do an empty spectrum
scan.

Equipment and obstacles: how to prevent measurement of interference signals
Do not put the device immediately above equipment and obstacles in a silo or pit. This can have
an effect on the performance of the device.
INFORMATION!
If possible, do not install a nozzle on the silo centerline.
