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
