To reassemble a hex-body meter, follow the steps below:
Insert a vane into the meter body, ensuring that the flow arrow is point
-
ing in the direction of flow and the marked blade is positioned at the
bottom of the bore (Figure 6, page 18). The vane should fit snugly but
should not require excessive force to install.
Insert a retainer ring behind the vane.
Insert the rotor into the opposite end of the meter body, ensuring that
the flow arrow is pointing in the direction of flow. Handle the rotor with
care to avoid chipping the rotor shaft.
Insert the second vane into the meter body, ensuring that the marked
blade is positioned at the bottom of the bore. Rotate the rotor if neces
-
sary to allow the vane to slip into position. Do not use force to drive the
vane into the meter body, as this can result in a broken rotor shaft.
Insert a retainer ring behind the vane.
Spin the rotor by hand. If the rotor does not turn freely or stops abrupt
-
ly, disassemble the meter and check the rotor for damage.
