The visual level indicator is filled with liquid from the tank. When filling the tank for the first time, bear in mind
that there will not yet be any liquid in the float outlet, and that the float will only float when this dead space
has been filled via the lower socket.
Once the float starts floating, some time will still be needed for it to align with the magnetic band of the
indication rail. From then on, the fill level should be shown when the gauge flaps are turned down.
If any of the gauge flaps are shifted into an incorrect position during transit, it is possible to move them back
to their intended locations using a weak hand-held magnet. This method can also be used to test the
mobility of the gauge flaps by hand. However, they should always then be put back in their original
positions.
It is advisable to completely drain the tank under supervision once, and to visually check the fill level so that
you can guarantee the level gauge is functioning properly.
Just to be on the safe side, check the entire device after it has been filled, including checking the seals for
leaks.
For steam applications, it is imperative that you ensure no pressure surges occur, as this may catapult the
float up into the float chamber and destroy it.
11. Maintenance

Only use the visual level indicator if it is working properly.

Do not use an unsealed visual level indicator.

Working on hot or pressurised visual level indicators may result in physical injuries, burns,
chemical burns or poisoning. Depressurise the tank and allow it to cool to the ambient
temperature before working on the visual level indicator. Wear suitable protective equipment
(gloves, face guard, possibly breathing apparatus).

If you suspect that there is a malfunction or determine that there is one, this must be rectified.
Damaged or faulty components must be replaced by original replacement parts.

The visual level indicator may only be repaired and modified by the manufacturer (or, if
appropriate, in consultation with the notified body).
The visual level indicator is generally maintenance-free.
The level gauge should only be cleaned on the outside – and on the inside if necessary – in the
event of a suspected malfunction, or in any of the circumstances listed below.
Time Scope
While in use
-
In the event of a suspected
malfunction
-
Periodically, depending on
usage and degree of
contamination
Check visual level indicator for leaks.
If required, clean inside and outside.
Check float for excessive wear marks.
Before each use Check for damage.
For highly-viscous and/or heavily
contaminated process liquids Periodically clean the inside, depending on degree of
contamination.
After a long period of inactivity Check visual level indicator for leaks.
If required, clean inside and outside.
After cleaning
(see chapter 12) Check visual level indicator for leaks.
