Abstract
Improved Coriolis mass flow sensor including a single connection and support structure having an in-line inlet and outlet and a one-piece, generally helical sensing tube structure wound in concentric fashion about the in-line axis of the support structure and supported relative thereto by tube ends affixed to ports formed in the support structure and in fluid communication with the inlet and outlet flow paths. The tube extends through approximately 720.degree. as it wraps about the centerline axis, and carries actuator means at its 12 o'clock position and sensors at the quarter hour positions on opposite sides of the device centerline. A pair of node plates are disposed at spaced-apart locations on the tube side opposite the actuator and serve to couple the centermost loop section to the downstream tail and the centermost loop section to the upstream tail, respectively.
