Flow Conditioning Devices

Selecting the right configuration for ultrasonic flow meters indeed poses various challenges, as highlighted in the detailed explanation. The factors to consider, such as swirl, crossflow, and pressure-loss implications, underscore the complexity of this process. The trade-offs between different conditioning devices, including their impact on axial profile, sensitivity to flow changes, and pressure loss, are effectively outlined. This information provides valuable insights for those involved in selecting and configuring ultrasonic flow meters.

CALDON Brownian Flow Conditioner (BFC)

Balancing your ultrasonic flow meter setup precisely can present challenges. Factors like swirl, crossflow, and pressure-loss penalties must be carefully weighed when selecting the appropriate conditioner to uphold the accuracy of your operations.

For example, chordal ultrasonic meters with four paths, utilizing Gaussian integration principles, are resilient to changes in the axial profile but are vulnerable to swirl and/or crossflow common when flow changes direction in a pipeline system.

Tube bundles, often employed in liquid applications, boast lower pressure loss in turbulent flow compared to conventional plate conditioners. Nevertheless, they can negatively impact the axial velocity profile and pose challenges in maintaining consistent manufacturing quality. Additionally, tube bundles lead to increased pressure losses in liquid applications within the laminar regime.

CALDON BFC Product Sheet

Caldon engineers have utilized their extensive expertise in ultrasonic meters and thorough research on various flow conditioners dating back to the 1960s to craft an optimized flow conditioner tailored for use with ultrasonic meters.

The patented BFC flow conditioner combines the reproducibility and performance benefits of a plate-style conditioner with the low-loss features of a tube bundle. Moreover, it eradicates the elevated frictional losses linked to the extended tubes seen in traditional tube bundles. In gas applications, where pressure drop impacts the creation of acoustic or audible noise, the BFC's notably decreased pressure drop and balanced hole geometry can alleviate noise challenges commonly faced with standard plate conditioners.

The BFC is intended for integration with other primary technologies, as long as adherence to international standards or qualifications is ensured. For tailored guidance, it's advisable to reach out to Sensia for expert recommendations and support.
