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 C5.1.2 Identification. For more data, refer to

Function description

number of the device (given on the device nameplate) and speak to the supplier.

Changes and effect on compatibility

1 Downwards compatible changes and fault repair with no effect on operation (e.g. spelling

mistakes on display)

LPR (Level Probing Radar) devices

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.).

3.1 Pre-installation requirements

INFORMATION!

Obey the precautions that follow to make sure that the device is correctly installed.

• Heat sources (sunlight, adjacent system components etc.) can increase the internal

temperature of the device and cause damage. Make sure that the internal temperature is not

more than the maximum limit. The maximum permitted ambient temperature is +80°C/
+176°F. The maximum permitted surface temperature is +80°C / +176°F.

• Do not subject the signal converter to heavy vibrations. The devices are tested for vibration

and agree with EN 60068-2-6. If there is vibration, we recommend that you use the electrical
cable clamp with a device hanger.

Figure 3-4: Recommended mounting position above a flow channel

If it is necessary to measure volumetric flow rate in the flow channel:

• Make sure that the flow channel agrees with one of the flow channel options available in the

device DTM (PACTware).

• Go to menu C3.1 Conversion Dry

"Volume Flow"

• Measure the dimensions of the flow channel and the position of the device above the flow

channel.

• Enter the measured values in the DTM and complete the procedure.

We recommend that you prepare the installation when the tank is empty.

3.5.1 General notes

CAUTION!

Do not install the device above objects in the tank (ladder, supports 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 How to make a filter to remove radar signal interference on page

.

INFORMATION!

If possible, do not install a nozzle on the tank centerline.

CAUTION!

Do not put the device near to the product inlet. If the product that enters the tank touches the
antenna, the device will measure incorrectly. If the product fills the tank directly below the
antenna, the device will also measure incorrectly.

INSTALLATION

If the device cannot go in the tank and the tank is made of a non-conductive material (plastic
etc.), you can attach a support to the top of the tank without a hole in the tank roof. We
recommend that you put the antenna as near as possible to the top of the tank.

CAUTION!

Do not hang and use this device above a plastic tank in bad weather conditions (rain etc.). Bad
weather conditions can have an effect on the device performance.

CAUTION!

We recommend that you do not hang and use this device above a plastic tank that has dust on it.
Dust can have an effect on the device performance.

Figure 3-9: How to attach the orientable device collar to the device

Equipment needed:

• Device

• Orientable device collar with a support fitting

• 10 mm socket wrench (not supplied)

• Loosen the two nuts on the device collar with the 10 mm socket wrench.

• Put the device in the collar. The position of the collar must give enough clearance above the

cable gland to prevent damage to the electrical cable. For more data, refer to

protection

• Tighten the two nuts on the device collar with the 10 mm socket wrench. Make sure that the

device cannot move in the collar.
