Air flow measurement is most accurate in straight duct runs where air flow can be evenly profiled across the duct at the point of measurement and where no turbulent, reverse, or cyclonic flow patterns are present. Typically, it can take as much as 10 diameters of straight duct run to eliminate turbulent or reverse flow, while it can take as much as 30 diameters of straight duct runs to eliminate cyclonic flow. If you do not have the proper amount of straight duct run present to accurately measure your air flow, some type of flow conditioner is required.

The HBP - High Beta^® Process Flow Conditioner is ideally designed for industrial process applications where the expansive straight duct runs needed for accurate flow measurement are not present. Perfect for new or for rerofit applications, the HBP is designed for installations with relatively no straight duct runs upstream or downstream and eliminates cyclonic , turbulent and reverse flow at the point of measurement. The HBP consists of a flanged duct section that can be inserted in to round ducts. An array of VAP^3®Pitots is housed within the HBP, allowing for an accurate differential pressure output that provides precise air flow measurement for tighter control of your process.

Engineered for a variety of duct sizes and configurations, the HBP is designed to be an accurate, dependable source for air flow profiling and measurement without the lengthy lead times associated with Engineered-to-Order products. Upon arrival onsite, the HBP can be quickly bolted in to place via its flanged spool section, which is manufactured with standard bolt patterns that will easily fit most duct configurations.
