7. INSTRUMENT MAINTENANCE
The Starflow QSD requires very little maintenance. During routine site visits, the following
checks can be performed:
Piezo element
faces
Clean the instrument surfaces where the Piezo elements are
located by wiping them with a cloth. If needed, a plastic scraper can
be used to remove any biofouling. Take care not to scrape the
surface of the instrument. Refer to the above diagram for the areas
where the ultrasonic eyes and conductivity sensors reside. These
areas must be kept clean.
The front face of the instrument and the area above the depth Piezo
should be clear.
Pressure depth
sensor
Check that the opening to the depth pressure sensor is clear of any
fouling. Use a brush to clear any material.
Conductivity
Electrodes
With a cloth wipe the electrode faces. Do not use abrasive materials
to clean them as this will affect the calibration of the conductivity
measurement.
Cable
Inspect the cable to ensure that it has not been damaged.
General inspection
Visually check the instrument to see that it has not been damaged
by heavy debris in the measured stream.
