Step 4: Mounting the transmitter
Now proceed with the installation of the transmitter
and antenna.
Protect from water:
The transmitter unit must be
installed in so that it is protected from water. For
outdoor systems, place the unit upright to prevent
water from entering the battery contacts.
Mounting:
Attach the transmitter to the tank or the
wall of the manhole chamber using the magnets
integrated in the battery pack (see arrows below)
(Fig. 5)
, or with the optional bracket.
Caution!
In Ex zone 1, the cable to the
sensor must be laid carefully to avoid
damage. Make sure that the cable is not
kinked or pinched and damaged when the
manhole cover is closed.
There should be a distance of at least 20 cm between
the device and the signal generator. Otherwise
there is a risk that the magnetic field of the sensor
system will be affected by the fastening magnets
and the measurement result will bedistorted.

Step 5: Mounting the antenna
Attach the external antenna to a metal surface
using the magnetic base
(Fig. 6)
. As a general rule,
the larger the metal surface, the better the trans-
mission power.
In order to achieve good transmission power, the
antenna should be mounted vertically (upright).
Make sure that the connection between the antenna
base and the metal surface is clean.
In the case of above-ground tanks, for example,
attach the external transmission antenna directly
to the container.
In the case of underground tanks, the antenna
should be attached outside the manhole chamber
e.g. attached to the manhole cover or safely
embedded into the ground using the optional drive-
over antenna. Inside the chamber, the signal can be
significantly restricted by the metal surroundings,
thus reducing the transmission range.
