The Ultraflow QSD 6537 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.
