DRY GAS METER AND METHOD OF ASSEMBLING A FLAG ROD

摘要

A flag rod assembly for transmitting the reciprocating movement of a diaphragm (13) out of a gas chamber comprises a straight flag rod (24) secured to flag (22) which in turn is pivoted to the diaphragm. An end stop (30), bearing (31) and shoulder (32) hold the flag rod and flag in position in their normal arc of movement. For assembly and disassembly the flag (22) may be rotated out of said normal arc whereby it is moved out of alignment with shoulder (32), allowing endwise movement of the flag rod.
