A parallel path Coriolis mass flow rate meter (10), which incorporates improved inlet and outlet manifolds (100, 100'). Each manifold includes a transition piece (110, 110') and a tube mounting block (120, 120'). The transition piece incorporates a passageway (303) 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 (130, 130'). One mounting block (120) evenly divides incoming fluid whose mass flow rate is to be determined between the parallel flow tubes while the other mounting block (120') combines the fluid discharged from the flow tubes. Each of the tube mounting blocks is fabricated with an internal shoulder (707) 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.read more

Jens Simonsen,Jan Zangenberg +1 more
TL;DR: In this paper, a mass flow measuring device for flowing media, working on the Coriolis principle, comprising a pair of essentially parallel measuring tubes (2, 3), is presented, where the measuring tubes are fixed to each other in the initial section (4, 5) and in the terminal section (11, 12) by at least one plate (17, 19' and 18, 20') over a continuous length in a plane essentially parallel to the longitudinal axis of the measuring tube, the length of which is greater than the separation between the measurements.

Parallel path Coriolis mass flow rate meter
TL;DR: In this article, a flow meter for measuring the mass flow rates of fluids passed through two essentially parallel, cantilever mounted U-shaped flow tubes where, instead of the fluid serially passing through one of the U-shape flow tubes and then through the second U shape flow tube, the fluid is essentially evenly divided and half of the fluids is passed through one U shape and the other half of them are passed through the other shape.

Meter for measuring mass flow rate
TL;DR: In this paper, a dynamic mass flow meter is described in which an S-shaped conduit with supported ends is vibrated in a direction transverse to the plane of the conduit, and the force couple about an axis orthogonal to the longitudinal axis of the Sshaped conduit and also to the direction of vibration is sensed as a measure of the mass flow rate through the conduit.
