HIGHBETA®

High Beta<sup>®</sup> gas flow measurement system is ideal for either new or retrofit industrial applications

High Beta® | Electronics | Other Options | High Beta® Video


High Beta®:

Air flow measurement is most accurate when the flow has no turbulent, reverse, and/or cyclonic flow patterns and is evenly profiled across the duct at the measurement point. The High Beta® flow conditioner is ideal for either new or retrofit process and power applications where insufficient straight duct runs are present and/or accuracy is required.

The High Beta® is a proprietary-designed flow-conditioning device with minimal pressure loss which accepts VAP3® Pitots and was designed for installations with relatively few or almost no duct runs upstream and/or downstream. The High Beta® eliminates cyclonic, turbulent, and reverse flow at the point of measurement. It is ideal for both new or retrofit process and power applications where insufficient straight duct runs are present and/or accuracy is required. The High Beta® allows the VAP3® Pitots to obtain their maximum accuracy.

Additionally, the High Beta® can be *NIST reference calibrated prior to installation. Typical *NIST calibrated total flow uncertainties can be as low as ±0.50% over the calibrated range. There are many different variations of the High Beta® that include specific product features for the pharmaceutical, process, and power generating industries. The High Beta® can also be engineered to meet specific application requirements. Read on to discover which High Beta® options are right for your application.

The High Beta® consists of a flanged 304 stainless steel duct section that can be inserted into either round or rectangular ducts. Within the High Beta® is housed an array of VAP3® pitots. The VAP3® provides an accurate differential pressure output, allowing for precise air flow measurement or control of your processes. The High Beta® is available with VAP3®/SA or VAP3®/PA pitots, for clean air applications or heavy particulate-laden applications, respectively. The High Beta® is erosion resistant, handling typical process temperatures from -40° to 700°F.

High Beta® Engineered

The High Beta® Engineered is a custom-built solution to air flow measurement problems, ideal for power plants. Our engineers evaluate the customer’s existing ductwork and can make recommendations using Computational Fluid Dynamics (CFD) Modeling. Flow profiles, temperature stratification and duct modifications can be modeled to improve measurement accuracy and process performance.

High Beta® Process Flow Element

The High Beta® Process Flow Element is ideal for process applications where a high level of accuracy is crucial. The HBP is available in medium pressure with a 30 psig (2 bar) rating, and flanges can be shock rated if needed. The HBP is constructed of 304 stainless steel and has flange options determined from the pressure rating and material thickness. Gasket options are also available.

Duct Section VAP3®

• Either VAP3®/PA or VAP3®/SA
• Duct mounted measurement with VAP3® Pitots installed in place, utilizing straightening vanes
• There is no converging section of the High Beta®
• Available in sizes from 4 to 36“ in 2-inch increments (custom sizes are available)
• Available in a number of material, flange, and pressure configurations

Electronics:

Differential Pressure System - DPS

High Beta gas flow measurment electronics.The DPS, when coupled to the VAP3® pitot, is used to deliver flow measurement for process and power applications. The microprocessor-based flow transmitter consists of a differential pressure transmitter and flow processor. The system transmits an analog output signal that is proportional to flow. The processor enables the DPS to take a temperature and/or a duct static pressure input signal, providing a density-compensated output signal in wide range of flow units. With the fast scan time of the DPS and a selectable moving average of the display and output variables, the DPS can deliver a reliable, accurate signal, converting the fast response of the VAP3® pitot to the digital control systems of today.

The DPS can be used in conjunction with the Line Mounted Purge (listed below).

Differential Pressure Unit - DPU

The DPU, when coupled to the VAP3® pitot is used to deliver accurate, dependable flow measurement in process and power applications. The Pressure and Flow Transmitter and Display Unit consists of a differential pressure transmitter and an optional display. The DPU can be configured to display differential pressure or flow rate and will transmit a 4-20mA analog output signal that is proportional to the displayed value. The DPU can also be configured to simply be an enclosed pressure unit with or without a display and transmit the actual differential pressure in a 4-20mA signal.

The DPU can be used in conjunction with the Line Mounted Purge (listed below).

Differential Pressure Gauge - DPG

The DPG, when coupled to the VAP3® pitot, is used to deliver a reliable flow measurement for process and power applications. The Pressure and Flow Display consists of a differential pressure gauge manifolded within an industrial enclosure. It can be configured to display differential pressure in inches of H2O, as well as flow rate in customer defined units.

The unit is accurate to within +/- 2% and is suited for clean, dry, non-corrosive air. It is rated for internal pressures from -10 to 10 psig (-68.6 to 68.9 kPa) and temperatures from 20° to 140° F (-6.67° to 60° C). When just a differential pressure display is needed, the DPG is the ideal solution.

Other Options:

Remote Temperature Sensor - RTS

The Remote Temperature Sensor (RTS) is a temperature-measuring device that can be remotely mounted to a duct or pipe via a half coupling. It is the perfect alternative when an integrated temperature option cannot be used with a VAP3® Pitot or when a High Beta® Flow-conditioning device is installed. When used with a DPS flow transmitter, the RTS can provide the temperature input when temperature and pressure correction are required.

Line Mounted Purge - LMP

The Line Mounted Purge (LMP) is a continuous purge system intended to be used with VAP3® Pitots by Eastern Instruments. The LMP is designed to supply a continuous balanced flow of air through the impulse lines and out of the probes sensing ports during flow measurement. The unit consists of an anodized aluminum purge block and capillary/internal filter set with ports tapped to receive NPT fittings, an optional mounting bracket (ordered separately), and a filter assembly.
