HBP - HIGH BETA PROCESS (INDUSTRIAL)
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 run 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 retrofit 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 spool section, a converging duct section, a set of straightening vanes and an array of VAP3® Pitots. The HBP ensures an accurate differential pressure output that provides precise air flow measurement for tighter control of your process.
