3.3 Transport

WARNING!

•

Depending on the version, the device will weight approx. 5...30 kg / 11...66 lbs. To carry, use both hands to lift the device carefully by the converter housing. If necessary, lift the device with a hoist.

•

When handling the device, avoid hard blows, jolts, impact, etc. to prevent damage.

3.4 Pre-installation requirements

INFORMATION!

The following precautions must be taken to make sure it is correctly installed.

• Make sure that there is adequate space on all sides.

• Protect the signal converter from direct sunlight and install the weather protection accessory

if necessary.

• Do not subject the signal converter to heavy vibrations. The devices are tested for vibration and agree with EN 50178 and IEC 60068-2-6.

INSTALLATION 3

To make sure that you install the device quickly, easily and safely, prepare the installation as given in the instructions that follow.

CAUTION!

Follow these recommendations to make sure that the device measures correctly.

Maximum distance of nozzle from the tank wall depending on:

1 1/3 x tank diameter 2 1/3 x tank diameter

5 Tank height

INFORMATION!

If possible, do not put 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.
