Maintenance; Storing And Cleaning Of The Sensor; Trouble Shooting Guide - Burkert 8045 Mode D'emploi

5.1 STORING AND CLEANING OF THE SENSOR

In correct installation conditions the 8045 flow transmitter is maintenance-free. If
contamination or clogging should occur during operation the sensor can be cleaned
with water or another cleaning agent compatible with the PVDF and SS316L.
It is highly recommended to perform a calibration of the zero point 24 hours
after the cleaning of the electrodes, or in cases of changes of the fluid.
The current output is set to 22 mA in case of an electronic failure and at the
start-up of the device all parameters are set to factory setting values (§ 4.6).
The reasons for failure can be seen within "Display 'ERROR' - output current
22mA" in the trouble shooting guide below.
