TLPR (Tank Level Probing Radar) devices only
Use approved personnel to install the device. The device and the tank agree with the R&TTE
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.
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 R&TTE 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.
Radio quiet zones: locations of radio astronomy sites (stations) in Europe and northern Eurasia
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.).
