The High Beta Engineered flow conditioner is a proprietary-designed flow-conditioning device that is designed to minimize pressure loss while straightening flow in combustion air flow ducts with relatively few or almost no straight duct runs upstream and/or downstream. Eliminating cyclonic, turbulent, and reverse flow at the point of measurement, the High Beta optimizes flow conditions so that the accompanying VAP Pitots can obtain their maximum accuracy.
The High Beta consists of a flanged 304 stainless steel duct section that can be inserted into either round or rectangular ducts. A converging section effectively straightens the flow profile and accelerates air through its round measurement area. An array of VAP pitots is housed within each HBE that will provide an accurate differential pressure output for the highest degree of air flow measurement and control of your process. The High Beta is erosion resistant and can handle typical process temperatures up to 700oF. 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.
THE HIGH BETA AND THE POWER INDUSTRY
The trend to improve efficiency in today's power plant environment drives the need for effective boiler trim controls which, in turn, requires accurate combustion air flow measurement.
