note 
After cleaning of the flow sensor:
• Rince the flow sensor.
• Check the seals and replace them if necessary.
• Before commissioning calibrate the flow zero point.
To prevent any measurement error due to deposits on the electrodes, clean the wetted parts regularly (cleaning 
frequency depends on the process).
