Abstract: Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. In some embodiments, the flowmeter includes a measurement section having a non-circular transverse cross-section in which one or more sensors for measuring flow are disposed. The non-circular measurement section can reduce distortion of ultrasonic waves, facilitate chordal measurements with flush-mounted transducers, and reduce the propagation distance between paired transducers. In some embodiments, the flowmeter includes a conditioning section with diametrically opposed longitudinal rib protrusions. The protrusions can reduce swirling flow, direct liquid components of a multi-phase flow towards the sidewalls of the flow path, and guide ballistic particles through the center of the flow path away from sensitive measurement devices.
Abstract translation: 本文公开的流量计包括一个或多个流路特征，用于改善流量计的测量精度或其他方面。 在一些实施例中，流量计包括具有非圆形横截面的测量部分，其中设置有用于测量流量的一个或多个传感器。 非圆形测量部分可以减少超声波的畸变，便于使用嵌入式传感器进行弦状测量，并减少成对的传感器之间的传播距离。 在一些实施例中，流量计包括具有直径相对的纵向肋凸起的调节部分。 这些突起可以减少旋转流动，将多相流的直接液体组分朝向流动路径的侧壁，并且将弹道粒子引导通过远离敏感测量装置的流动路径的中心。

Abstract: Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. A flowmeter can include an elongate body having a first end and a second end and a flow path extending between the first and second ends along a longitudinal axis. An ultrasonic transducer can be disposed in a measurement section of the flow path and configured to emit ultrasonic waves into a material flowing through the flow path. First and second protrusions can be formed in a conditioning section of the flow path upstream from the measurement section, the first and second protrusions extending radially inward from a sidewall of the flow path and being configured to reduce swirling flow through the measurement section.
