7.0 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 with a cloth. If needed a plastic scraper can be used to remove
any bio-fouling. 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.
