Maintenance / Maintenance plan

Intervals for replacing wear parts

DS08 type flow monitors require very little maintenance due to the small number of mov-
ing parts. The intervals for the replacement of wear parts depend significantly on the oper-
ating conditions as well as on the composition of the medium flowing through the device.
For this reason, no intervals have been set by the manufacturer. The operator must
determine suitable intervals based on the local conditions and circumstances.

Maintenance work:



Visual inspection for dirt/soiling



Visual inspection for free movement of float



Visual inspection for leaks from the device



Check function of switch contact

For detailed information on maintenance and cleaning of the device, please refer to
a separate manual. Please ask for them if required.
