10.2 Routine Maintenance
The sensor will require routine cleaning; the frequency of cleaning is site dependent and should be determined by
observation of the sensor during the first few weeks of operation.
Typically the sensor should be cleaned once per fortnight, although on many sites once per month is sufficient.
The sensor can be cleaned using a soft cloth; no special cleaning materials are required.
Care must be taken to ensure that no loops of cable are displaced during cleaning and the sensor should be lowered
carefully into the tank after cleaning.
