3.4.1  Mounting of the sludge level meter

Due to many different applications and installation points of sludge level meter a standardised 
mounting is often not applicable. To overcome the problem of the local conditions three different 
opportunities exist to order the mounting of the sludge meter.

INFORMATION!

To ensure proper assembly, please use only the mounting material provided with the meter.

INFORMATION!

All bolts, nuts and washers should be greased to prevent cold welding and ensure simple 
disassemble after use.

INFORMATION!

Please ask a second person to help with this procedure.

INFORMATION!

Ensure that the handrail is suitable for the weight of the mounting frame and the device 
(standard: 26.5 kg / 58.4 lbs, with cleaning unit: 31kg / 68.3 lbs); otherwise support the handrail 
with additional material. The operator is responsible for safe installation, especially against the 
fall in the sedimentation basin.
