The DM08 has no parts which have to be replaced or adjusted regularly.
Even though the units are maintenance-free, it is recommended to check the flow meter for signs
of corrosion, mechanical wear and damages at regular intervals.
We recommend routine checks at least once annually.
To clean and visually inspect the electrodes and the interior lining, the unit has to be removed from
the pipeline.
CAUTION! Risk of injury!
Perform all installation and connection work only when the supply voltage is switched off.
The connection between sensor and display electronics under voltage must not disconnected or

CAUTION! Risk of injury or material damage!
When removing the unit from the pipeline, take appropriate safety precautions. Always use new
gaskets during the new installation in the pipeline.
