Claim:
1. A vortex flowmeter comprising: a first process connection having a meter inlet therein, the first process connection being configured to connect the meter inlet to an end of an upstream pipe segment of a fluid pipeline; a second process connection having a meter outlet therein, the second process connection being configured to connect the meter outlet to an end of a downstream pipe segment of the fluid pipeline; a fluid conveyance system for conveying fluid from the meter inlet to the meter outlet, the fluid conveyance system including multiple separate passages configured to divide fluid received by the meter inlet into multiple separate fluid streams and convey the fluid in each stream to the meter outlet; a bluff body for each of the separate passages, each bluff body being positioned to generate vortices in the respective fluid stream; a sensor for each of the separate fluid passages that is configured to detect vortices in the respective fluid stream; and a processing system configured to determine a flow rate through each of the fluid streams using information from the sensors; wherein the first and second process connections are configured to connect the flowmeter to a fluid pipeline having a diameter that is at least 10 inches.
