5. For Flange Fittings - Customer to provide:
• Ring Gaskets or Full-Face Gaskets approved for use with
ANSI flanges and the fluid being monitored (two required).
• 5/8" bolts and nuts: Four per side for 3-inch meters; eight
per side for 4-inch meters.
Torque bolts using a star pattern to 25 ft-lbs. Supplied
flanges are two-piece and allow the meter to be oriented
regardless of the mating flanges position.
MAINTENANCE
Proper handling and care will extend the life and service of the
meter.
Turbine Rotor
The meter is virtually maintenance-free. However, it is impor-
tant the rotor moves freely. Keep the meter clean and free of
contaminants.
The rotor can be removed for cleaning and inspection. Begin
by unscrewing the nose cone from the outlet end of the meter.
A 1/4" square socket extension can be used. Remove the lock
and flat thrust washers. Rotor can then be removed from shaft.
Note orientation because rotor is not bi-directional. Remove
debris or deposits using soft brush or small probe. Reassemble
in reverse order.
CAUTION
Blowing compressed air through the turbine assembly
could damage the rotor.
