1.1 Software history
"Firmware revision" agrees with NAMUR NE 53. It is a series of numbers used to record the revision status of embedded software (firmware) in electronic equipment assemblies. It gives data on the type of changes made and the effect that changes have on compatibility.
Data about software revisions is shown in menu 1.1.0 IDENT. For more data, refer to Function description on page 66. If it is not possible to refer to the device menu, record the serial number of the device (given on the device nameplate) and speak to the supplier.

OPTIWAVE 7500 C 
INFORMATION!
LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic tank etc.). TLPR (Tank Level Probing Radar) devices measure level in a closed space only. You 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 144.
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. Refer also to the table that follows:

SAFETY INSTRUCTIONS 1
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.).

INFORMATION!
LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic tank etc.). TLPR (Tank Level Probing Radar) devices measure level in a closed space only.
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. Refer also to the table that follows:

LEGAL NOTICE!
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following conditions:
1.this device may not cause harmful interference, and
2.this device must accept any interference received, including interference that may cause undesired operation.
This device and the handbook complies with the requirements of RSS-Gen. Operation is subject to the conditions that follow:
1.The installation of the LPR/TLPR device shall be done by trained installers, in strict compliance with the manufacturer’s instructions.
2.The use of this device is on a "no-interference, no-protection" basis. That is, the user shall accept 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 installation only at fixed locations.
5.The installer / user of this device shall ensure that it is at least 10 km from the Dominion Radio 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.

2.2 Device description
This device is an 80 GHz FMCW-radar level transmitter. It is a non-contact technology and is 2- wire loop-powered. It is designed to measure the distance, level, mass, volume and reflectivity of liquids, pastes and slurries. For more data about the measuring principle, refer to Measuring principle on page 111.
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 Technical data on page 111.
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.
Figure 2-2: Types of antenna
1DN20 (¾¨) Lens antenna made of PEEK.
2DN25 (1¨) Lens antenna made of PEEK.
3DN40 (1½¨) Lens antenna made of PEEK. An antenna extension (length 112 mm / 4.4¨) is available for high nozzles.

CAUTION!
Follow these recommendations to make sure that the device measures correctly. They have an effect on the performance of the device.
We recommend that you prepare the installation when the tank is empty.
3.7.1 General notes
LPR and TLPR devices
WARNING!
LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic tank etc.). TLPR (Tank Level Probing Radar) devices measure level in a closed space only. You 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.
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 89.
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.
INFORMATION!
If possible, do not install a nozzle on the tank centerline.
