5.2 Of the metering body
The following faults may be appear:

Magnetic coupling deterioration,

Deterioration of the torsion or reading spring,

Wearing out of torsion shaft bearings,

Wearing out or deterioration of the lever and target disk.
If any of these breakdowns occurs, it is preferable to repair it in TECFLUID S.A.
workshops, as a new calibration will be normally necessary.
6 CLEANING
In line
Pass the normal cleaning agent through the installation.
In the workshop
It should be done with soft brushes. Never use sharp objects or metal brushes.
