EASTERN INSTRUMENTS INDUSTRIAL INDUSTRIAL AIR FLOW AIR FLOW PRODUCTS & PRODUCTS & TECHNOLOGY TECHNOLOGY Precision Air Flow Measurement Devices

Material Handling Solutions About Eastern Instruments Eastern Instruments, a Certified Women’s Business Enterprise, is an engineered solutions company located adjacent to the North Carolina International State Port in Wilmington, North Carolina. Since 1984, we have been engaged in the design and manufacture of devices that accurately measure and profile the flow of air and gases in the industrial and power sectors. These devices have been integrated into a variety of systems for regulating operations and improving efficiency across nearly every industry. Every device within Eastern...

Why choose an Eastern Instruments Air Flow Measurement Device? Accuracy Because all Eastern Instruments' flow measurement devices are based on the accuracy delivered by the VAP3® Pitot, all of our devices are extremely accurate and can measure flow to within ±2.00% or better when calibrated. Plug-Resistance When installed in the PA (Particulate Application) mode, the VAP3® Pitot has no impact ports which offer a plug resistant design that rarely requires the use of expensive purging systems. Parallel Plate Cross Sectional Design The VAP3® Pitot's unique cross sectional design minimizes...

Insertion Style Pitots The VAP3® Pitot comes in a variety of models, each designed to accurately measure the flow of air or gas under particular circumstances. Whether measuring clean air or air that is particulate-laden, the VAP3® pitot delivers an extremely accurate differential pressure output. The standard VAP3® pitot is constructed out of Anodized Aluminum for maximum durability, however, both PVC and Stainless Steel versions are available for caustic applications or where temperatures within the duct may reach up to 900o F. All models of VAP Pitots can be utilized in both round ducts...

EASTERN INSTRUMENTS Pitot Installation: Round Ducts Insertion Port: Curved Radius Bull Nose Port: Round Ducts An insertion port is typically welded to the exterior of a duct and pitots are then bolted to the insertion port. A curved radius allows the port to be easily mounted to the exterior of round ducts. A Bull Nose receiver and port is typically used on round ducts over 34" in diameter and helps to stabilize and support the pitot inside the duct. The Bull Nose Receiver is welded to the exterior of the duct just like the insertion port and the pitot's bull nose is inserted into the...

Flanged Duct Sections The Duct Section VAP3® (DSV) is a flanged duct section which includes an integral array of VAP3® pitots. The DSV allows for the easy installation of pitots within both new or existing duct work. Whether inserting the DSV into either Carbon Steel or Stainless Steel duct work or into air streams with extreme heat or that contain caustic gases, there is a DSV which will work for your specific application. The DSV can be utilized in both round or in square or rectangular duct work for accurate flow measurement when the recommended upstream and downstream straight duct runs...

Flow Conditioners The High Beta® Flow Conditioner incorporates both a converging/nozzled duct section for flow profiling, as well as an integral flow straightener in order to eliminate cyclonic flow at the point of measurement. The air, once straightened, passes through the element to the integral pitot array which accurately measures the flow of air in any circular duct in a fraction of the space that alternative technologies require. With the High Beta® Flow Conditioner, you can accurately measure flow with virtually no upstream or downstream straight duct runs. CS/SS Flanged Spool...

Air Flow Options MATERIAL OF CONSTRUCTION Pitots and Spool Section Depending on the application, most of the spool sections for our DP Based flow measurement devices can be constructed out of Aluminum, Carbon Steel, Stainless Steel (either 304 or 316), or PVC. The pitots themselves can be manufactured out of Anodized Aluminum, Stainless Steel or PVC. If your ducts are constructed of another material or if your flows contain caustic materials that will react with these materials, other materials of construction may be available. Coatings A variety of coatings are also available for coating...

QVT™ Multivariable Transmitter The QVT™ Multivariable Transmitter from Eastern Instruments is a Smart Transmitter that can be used for the accurate measurement of up to four separate process variables including Differential Pressure, Temperature and Absolute Pressure. When coupled with any DP based flow measurement element, the QVT will calculate the fully compensated mass flow of air/gas travelling through any process which is at or near atmospheric pressure (5 - 25 psia). The QVT is uniquely designed for high accuracy at low DP ranges and can accurately measure differential pressures down...
