Disassembling the Hex-Body Meter
Assembly and disassembly procedures vary with the type of flowmeter
installed. For instructions on repairing a round-body meter, see page 19.
To disassemble a hex-body meter, follow the steps below.
Remove the retaining ring from one end of the meter body.
Remove the vane from the meter body. Some slotted meters may
require a slight twist of the vane to align the vane with the slot in the
meter body. (If the vane is stuck, insert a brass rod through the opposite
vane and the rotor and tap on alternate blades of the vane to loosen.)
Remove the rotor. Handle with care to prevent damage to the shaft.
Remove the retaining ring from the other end of the meter body.
Remove the second vane from the meter body.
Examine the carbide bearing and rotor shaft. If either part is worn or
damaged, replace all internals with a repair kit (page 27).
