Eastern Instruments Duct Velocity Averging Pitot Tube for Clean Air VAP³®/SA

Eastern Instruments' VAP3® Pitots have a unique Velocity Averaging and Parallel Plate proprietary design. When inserted in air flow ducts, the VAP3® Pitots provide an accurate, differential pressure output allowing for precise air flow measurement or control of your process. VAP3® Pitots are designed for Superior Accuracy (SA) for clean air applications or plug resistant (PA) for heavy particulate-laden applications. The VAP3® Pitots can be installed in existing or new ducts or incorporated into flow-conditioning devices, such as the High Beta®, designed for short duct run applications with turbulent air flow or to obtain optimal accuracy. Each VAP3® Pitot has multiple total and static sensing ports, specifically located to provide a full traverse of the duct, thus eliminating the concern of highly random distribution of air flow. For larger ducts, an array of pitots, with total and static pressure lines manifolded, can be installed to ensure an equal area traversing and fully averaged air flow sampling. The VAP3® Pitots are erosion resistant and can handle typical process temperatures from -40° to 700°F. Other engineered options are available for temperatures outside this range. The VAP3® Pitots are constructed from a single-piece series 6063 aluminum extrusion that has a Teflon® (DuPont) impregnated hard-anodizing metallurgical surface treatment applied, yielding a surface hardness of Rockwell 65C. VAP3®/SA - SUPERIOR ACCURACY (CLEAN AIR APPLICATIONS) A proprietary design for relatively clean air applications and for Superior Accuracy (SA), the VAP3®/SA air flow measurement pitots are ideal for either new or retrofit process applications. When inserted in air flow ducts, the VAP3®/SA provides an accurate, differential pressure output allowing for precise air flow measurement and control of your process to as low as ±0.50% when calibrated. The VAP3®/SA pitots can also be incorporated within flow-conditioning devices, such as the High Beta®, designed for short duct run applications with turbulent air flow, or to obtain the maximum accuracy.
