MAINTENANCE

21.1

Series SC250

To perform the maintenance of the meter, it is necessary to remove some parts of the
flowmeter. Check below drawings for reference.
In flowmeters up to DN80 remove the circlip (6) which locks the top float stop (7). Then
remove the float stop (7). The float (2) can now be extracted. Check it is in perfect condition.
For flowmeters DN100 or larger sizes, remove the screw (9) which holds the float end (8).
Then remove the float end (8). The float (2) can be extracted from the top of the flowmeter.
Clean the magnetic cylinder (10).
In both cases also check the status of the calibrated orifice (3).
They should have no impact or scratches. Also check that there has been no chemical
attack.
If the float (2) is in poor condition it must be replaced. If the calibrated orifice (3) is also in
poor condition, the meter body (5) and float (2) should be replaced. In both cases we
recommend to re-calibrate the instrument in Tecfluid S.A. facilities.
To remove adhered chemical dirt to the float (2), metering tube (5) or calibrated orifice (3),
clean the parts with suitable products or solvents and soft brushes, never use metallic tools.
Follow the above steps in reverse to reassemble the equipment.
