Disassembly
Important: It is not necessary to remove window tube or window
seals to clean the meter. Note also how the meter
disassembles for easy of reassembly.
Warning: Shut down system before removing meter from flow line.
1. Use a clean dry cloth
to remove all foreign
material from exterior
of meter, especially
around threaded ends.
2. Remove meter from the
flow line.
3. With the arrow on the
scale pointing upward,
mount the meter in a
vice. See Illustration 3.
Use the flats of the inlet
end porting when securing the meter in the vice.
Important: DO NOT wrench or tighten vice on Lexan tube.
4. Install a wrench across the flats of the outlet end porting and turn
counterclockwise to loosen assembly. Do not remove end porting
at this time.
5. Remove meter from vice. Hold the meter so the end port that is
loose, is on top. Remove loose end porting.
6. Tilt the open end of meter
over a clean cloth to
expose inner cartridge.
See Illustration 4.
Remove inner cartridge
assembly from body
casing. Note: Because
the transfer magnet is
magnetically coupled to
the magnetic follower,
you will notice a slight
resistance when removing
cartridge. If cartridge does
not slide out, insert a wooden dowel in opposite end of meter and
push or lightly tap on dowel until cartridge comes loose.
