A parallel path Coriolis mass flow rate meter, which incorporates improved inlet and outlet manifolds, is disclosed. Each manifold includes a transition piece and a tube mounting block. The transition piece incorporates a passageway to route fluid into or out of the meter and has a gradually changing cross-sectional area to reduce cavitation. Each tube mounting block has one end fixedly attached to a respective one of the transition pieces. The other end of the tube mounting blocks receives the parallel flow tubes. One mounting block evenly divides incoming fluid whose mass flow rate is to be determined between the parallel flow tubes while the other mounting block combines the fluid discharged from the flow tubes. Each of the tube mounting blocks is fabricated with an internal shoulder which aligns each of the flow tubes in a parallel relationship to one another and then suitably melts upon application of heat to maintain this relationship. The mounting blocks and transition pieces also incorporate various mechanical configurations which facilitate assembly of the meter and advantageously reduce the cost of the meter. |
