Maintenance and service

All Sensyflow measuring systems are precisely calibrated for the respective application with our own ca-
libration equipment, for which ABB Automation is associated with the German Calibration Service. Exten-
sive calibration procedures, state-of-the-art production and testing procedures and continuous
enhancements guarantee that these measuring systems are operating over extended periods almost
maintenance-free. Only gases with moist impurities may cause the transducer to require occasional cle-
aning (depending on the dirt accumulation degree).

8.1 Cleaning the transducer

Follow these steps to clean the transducer or its sensor unit:
1. Disconnect the transducer. Power to the device has been removed; the sensor is no longer heated.
2. Dismount the transducer from the pipe component respectively weld-on adapter.
3. Clean the sensor unit with warm water or alcoholic solutions. It is recommended to use a soft brush
4. Allow the sensor unit to dry a few minutes or blow-dry.
5. Check the sealing between transducer and pipe component or weld-on adapter for proper condition
6. Mount the transducer in the pipe component or weld-on adapter.
7. Switch on or connect the transducer.
The measuring system is ready for operation again.
