9.1 Mounting
1. Lay out the tools, lifting aids, screws, nuts and seals that you need to
install the visual level indicator.
2. Position the visual level indicator on the tank. When doing so, make
sure that the TOP sticker on the indication rail is pointing upwards.
3. If needed, add seals to the connection threads or between the flange
connections.
-
Flange connections
Tighten the flange connection screws diagonally. Check that the
screw connections are a tight fit.
-
Weld sockets
Remember that heat will be built up when welding weld sockets.
Components at risk should be covered, cooled, or temporarily
removed.
-
Screw-in threads
The visual level indicator and indication rail must not be used to
provide counter torque when installing the screw-in threads. Use a
suitable tool for counteraction without putting stress on or damaging
mounted parts.
9.2 Inspecting
For all types of installation, make sure that the process connections for the
visual level indicator are aligned with the tank’s process connections.
The visual level indicator must be installed in a vertical position. You can
check this with a spirit level on the float chamber. Deviations of up to 5° from
the vertical position are acceptable. Larger deviations may result in increased
friction on the float in the float chamber and may lead to blockages. It is
imperative that this is agreed with the supplier.
Twisting or bending of the float chamber, caused by incorrect socket
distances for example, may block the float and lead to the visual level
indicator breaking down!
10. Commissioning
Installation (point 8 to point 9) must be fully completed before commissioning.

If the data marked on the type plate (density, max. operating pressure, max. operating
temperature, connection dimensions, material, etc.), does not match the application, the visual
level indicator may display an incorrect level, and it may be damaged and pose a risk to people
and the environment. Make sure that the data marked on the type plate matches the application.

Check the visual level indicator for visible external damage before use. Do not put a damaged
visual level indicator into operation.

The visual level indicator may only be used for the purposes recorded on the type plate and the
Ex label.
