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 VAP Pitots. The HBP ensures an accurate differential pressure output that provides precise air flow measurement for tighter control of your process.

TECHNICAL INFORMATION
Below, you can find the manuals for the High Beta family of flow elements. The manuals have been divided into the Mechanical Manual for the element itself and the Electronics Manual for the use and installation of any transmitter that was purchased from Eastern Instruments.
Below are just a few of the many features and benefits of installing a High Beta flow element within your process. If you have an application that you would like to discuss, please Contact Us today.
The High Beta Process (HBP) is mounted within a flanged spool section for any round ductwork up to 36 in in diameter.
The accuracy of the High Beta comes from the combination of the converging duct section and the integral flow straightening vanes that eliminate cyclonic flow. The flow is fully conditioned prior to flow measurement, thus practically eliminating the need for upstream and downstream straight runs.
The accuracy of the High Beta is typically within +/-0.5% and repeatability is within +/-0.1%, and that is achievable independently of the upstream and downstream straight runs.
Includes a flanged duct section for easy bolt in installation.
The High Beta includes an integral array of VAP Pitots that measure the air flow passing through the flow element. The pitots are available in either the SA mode for clean air flow applications or in the PA mode for "dirty" air or particulate-laden applications.
The High Beta contains an array of integral flow straightening vanes that eliminate cyclonic, turbulent and reverse flow at the point of measurement.
The High Beta and the duct section are made of Stainless Steel while the internal array of pitots are manufactured out of Anodized Aluminum, Stainless Steel or PVC.
Yields a pressure drop of less than 30% of the differential pressure generated across the flow element.
There are no active electronic components or moving parts that are installed within the air stream, thus eliminating maintenance costs and ensuring reliability and ease of use for many years.
VAP Pitot arrays provide multiple DP sensing ports along multiple sensing probes in order to offer full coverage, or full traversal, of any duct.
HBP APPLICATIONS - PROCESS
The High Beta Process is specifically for installation in round duct work often found in the process industry. The High Beta Process is generally used in applications where there are little or no straight duct runs or in applications where high accuracy is a necessity.

WHAT MAKES A HIGH BETA A HIGH BETA?
The High Beta for process applications (HBP) is a flow conditioning device that ensures that the integral flow measurement pitots mounted within it can measure flow as accurately as possible. The High Beta consists of a converging section of duct with flow straighteners mounted within the converging section. This patented arrangement ensures accurate flow measurement with little nearly none of the straight runs, which are typically required for other flow element installations.
The HBP is equipped with VAP pitots which can be installed in both a clean air mode (SA) or a particulate-laden air mode (PA), which place the HIGH port in-line with airflow, ensuring that no ports are considered impact ports and are thus, resistant to the plugging issues associated with standard pitots.
