Disassembling the Meter
12. The Universal Joint is an extension used to connect
the blocking rotor of the meter to the packing gland.
When the blocking rotor rotates, the Universal Joint
causes the packing gland to rotate which drives the
register. This assembly extends through the back of
the meter and into the weldment wall through the
drive coupling bearing.
