3. Check the float.

Floats with heavy signs of wear need to be replaced occasionally. When
ordering replacements, make a note of the serial/order number and the
item number to make clear assignment possible.

If the density noted on the float doesn’t match with the density of the fluid,
the visual level indicator will show an incorrect fill level. Consult your
authorised WEKA dealer before using a float from a different visual level
indicator.
An incorrectly installed float will lead to the incorrect fill level being
displayed!
4. Slide the float into the float chamber as shown.

Unsuitable screws, nuts and seals may result in leaks and cause damage
and may endanger people and the environment. Only use components
suited to the application.
5. Reseal the service connection, as described in point 9.1.
Recommission the visual level indicator, as described in point 10.
12.3 Cleaning the float chamber and float for a top-of-tank assembly

Risk of burning! Working on hot visual level indicators may result in physical injuries and burns.
The surfaces of the standpipes and the process connections may become hot. Allow the tank to
cool to the ambient temperature before working on the visual level indicator. Wear suitable
protective equipment (gloves, face guard, possibly breathing apparatus). Keep a sufficient
distance away while the machine is in operation.

Visual level indicators run at excessive pressure carry pressure-related risks. Depressurise the
tank before working on the visual level indicator and observe the information of the local valid
pressure regulations, i.e. Pressure Equipment Directive 2014/68/EU.

When opening the visual level indicator, bear in mind that the fluids and gases it contains could
be hazardous to health. It is imperative that you comply with the safety data sheets for the
process liquids and gases used.

Falling parts (screws, floats, etc.) may create impact sparks and lead to an explosion in
potentially explosive atmospheres. Make sure that there isn’t a potentially explosive atmosphere
and that no parts are falling when working on the visual level indicator.
1. Remove the visual level indicator.
2. Loosen the lower float stopper (usually a screw in the guide pipe which stops
the float from falling out) until you can remove the float.
3. Clean the float chamber and the float system with a suitable cleaning agent.
Check the float system (floatation panel, connecting pipe and magnet holder)
for damage and replace them if needed.
Floats with heavy signs of wear need to be replaced occasionally. When
ordering replacements, make a note of the serial/order number and the item
number to make clear assignment possible.
