6.4 Installation of the unit with single probe
For the correct function when used with single probe, the unit needs a
large enough metal launching plate� It is necessary for transferring the
microwave pulse to the tank with optimum transmission power� The flange
plates that are available as accessories are not sufficient as launching
plates�
For installation in closed metal tanks, the tank lid serves as a launching plate (R in
fig� 6-5 and 6-9)� 2 ways of installation are possible:
• Screw in a G¾ process connection in the tank lid (→ 6.4.1).
• Installation in the tank lid using a flange plate, e.g. for tanks with thin walls (→
Furthermore, installation in open tanks (→ 6.4.3) and plastic tanks is possible (→
6.4.1 Installation in closed metal tanks (without flange plate)

►
The lower edge of the process connection should be flush with the installation
environment (fig� 6-5)�
►
Avoid non-flush installation (fig� 6-6)�
►
Use seals or washers (D in fig� 6-7) to reach the required height�
►
For tanks with thick walls arrange for sufficiently deep recesses to ensure flush
installation�
