MODIFICATION OF AN ORIGINAL
Eastern Instruments' VAP3® Heated Pitots integrate modifications to the original VAP Pitot that allow them to work in conditions where most pitots freeze or begin to function less than accurately. The standard VAP3® Pitot has a unique Velocity Averaging and Parallel Plate proprietary design and, when inserted into air flow ducts, they provide an accurate, differential pressure output allowing for precise air flow measurement or control of your process. The Heated Pitot utilizes this same VAP3® Pitot technology in order to deliver an extremely accurate differential pressure output, while expanding the traditional temperature ranges handled by the original pitot. The Heated Pitot, with integral heating system now allows accurate air flow measurement down to -22o F!
The Integral Heated Pitot can be installed in clean-air or particulate-laden applications, and will typically still retain the accuracy of our original VAP3® (±2%), even when installed in locations where ice build up is present. The heating system integrates a heat tracing element into the pitot itself so that problems with ice build-up simply...melt away. Because the pitots are not prone to freezing over, the surface area of the pitot is not affected by accuracy damaging, or even flow measurement eliminating effects of ice-build up, and therefore, the accuracy of the Heated Pitot is unaffected by the onslaught of conditions like freezing rain, or even the extreme temperatures surrounding cooling towers.
FEATURES AND BENEFITS
GREAT FOR FREEZING TEMPERATURES - The VAP3® Heated Pitot can prevent freezing of the pitots down to -22o F and is perfect for regions that routinely see freezing temperatures.
VERSATILE DESIGN - Due to the VAP3® Heated Pitot's unique design, they can be utilized in both clean air applications as well as in particulate-laden applications.
PARALLEL PLATE CROSS SECTIONAL DESIGN - Minimizes turbulence at the sensing ports, preventing particulate build up and also designed for high turndown applications.
MULTIPLE DIFFERENTIAL PRESSURE SENSING PORTS - Velocity averaging throughout the full traverse of the duct with multiple pitot array.
DURABLE MATERIALS OF CONSTRUCTION - Constructed from extruded 6063 series aluminum with a final process Teflon® hard anodized coating, yielding a surface hardness of Rockwell 65C.
BASIC INSTALLATION - Each VAP3®/PA and VAP3®/SA Pitot probe can be inserted into the duct utilizing a pre-fabricated weld on insertion port. When multiple probes are needed within the duct, the total and static sensing ports can be manifolded together.
NEGLIGIBLE PRESSURE LOSS - Due to the streamline, narrow cross-section of the Parallel Plate Pitot design, the VAP3®/PA and VAP3®/SA will not restrict the airflow, therefore there will be minimal, if not negligible pressure drop across the measurement area. Integrated temperature elements are available to further reduce in-duct obstructions.
INDEPENDANT PITOT CONTROL - For installations where multiple pitots are required, one SSR is installed in the control package for each of the installed pitots meaning that you can maintain temperature control over each individual pitot in the array.
HIGH/LOW TEMPERATURE ALARMS - Contacts for both High and Low Temperature alarms are available in order to maintain control of the Heated Pitots to ensure that they do not freeze and that they do not overheat as well.
