ABSTRACT:
A flowmeter alignment device comprises an alignment ring affixed to an end of a flowmeter flowtube and having spring fingers to engage the circumference of a pipe flange raised face. In another embodiment a flowmeter alignment device comprises a semicircular or other arcuate body affixed to the flowtube end, the arcuate body adapted to mate with the circumference of a pipe flange raised face. The arcuate body is shaped to permit lateral installation and removal of the flowtube from a mating pipe flange. In still another embodiment an alignment ring is adapted also for use as an electrical grounding ring for electromagnetic flowmeters, or as an orifice plate for differential pressure-based flowmeters.
