Tecfluid FLOMAT Series - Manual (Page 11)

8 MAINTENANCE
It is recommended to clean the electrodes in installations where appreciable incrustations
or sedimentations can occur. Dirty electrodes can cause unstable readings and in extreme
cases indication of empty pipe detection
Cleaning can be done using liquid detergents and medium hard brushes.
The Flomat-Tap System allows maintenance of Flomat sensors without having to stop
flow of the liquid in the pipe. If you have one of these, refer to its instruction manual for
operation.
