MAINTENANCE
The SulfiLogger
™
sensor has no active fouling handling, and the
sensor head therefore needs periodic cleaning. The necessary
cleaning frequency depends very much on the type of wastewater
and on the turbulence around the sensor. Stagnant water gives
ideal conditions for biofouling, and when choosing a mounting po-
sition it is therefore advisable to look for a position with relatively
high flow / turbulence.
For new installations it is recommended to clean and calibrate
the sensor one time per week to ensure stable operations. When
more experience has been gained on the actual fouling rate at the
installation site, this maintenance frequency may be changed.
CLEANING
The SulfiLogger™ sensor’s durable design makes cleaning easy.
•
Remove any accumulated rags/fibers and larger debris from
the sensor.
•
Wipe off the sensor head with a cloth. Take special care to
ensure that the inlet slit(s) at the front of the sensor head is
completely clean.
•
If needed use water or a mild soap to clean the sensor head.
This is especially important if a greasy layer has build up
on the sensor or if a layer of biofilm can be directly seen.
Ethanol can also be used.
CALIBRATION
The SulfiLogger
™
sensor comes factory calibrated and is as such
ready to use immediately as received. However, calibration in
