INFORMATION!

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. The LPR and TLPR devices meet the requirements of the RED (Radio Equipment Directive) for use in the member countries of the EU.

For more data about the order code, refer to Order code on page 164

This level transmitter is approved to be used outside metallic tanks. If you use the device in the open air, read the device nameplate to make sure that the device can be used for your application. Only the antennas that follow are permitted for open-air applications:

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.

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.).

FCCFCC 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.

•

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 8

Causes of interference signals

• Objects in the tank or pit.

• Sharp corners that are perpendicular to the path of the radar beam.

• Sudden changes in tank diameter in the path of the radar beam.

TLPR (Tank Level Probing Radar) devices measure level in a closed space only. You

INSTALLATION

CAUTION!

Do not install the device above objects in the tank (agitator etc.) or pit. Objects in the tank 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 tank or pit, do an empty spectrum scan. For more data, refer to Empty spectrum recording on page 102

Equipment and obstacles: how to prevent measurement of interference signals

Do not put the device immediately above equipment and obstacles in a tank or pit. This can have an effect on the performance of the device.
