VAP HEATED PITOT: FEATURES AND BENEFITS

VAP Heated Pitot for accurate air flow measurement in ducts prone to extreme cold
Heated Pitots incorporate modifications to the original VAP Pitot that allow them to accurately measure, even in conditions where most pitots freeze or begin to function less than accurately. The standard VAP Pitot has a unique Velocity Averaging and Parallel Plate proprietary design that, when inserted into air flow ducts, provides an accurate differential pressure output that allows for precise air flow measurement and control of your process. The Heated Pitot utilizes this same VAP 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!


FEATURES AND BENEFITS






FEATURES AND BENEFITS

  • GREAT FOR FREEZING TEMPERATURES: The VAP Heated Pitot can prevent the freezing of pitots down to -22o F and is perfect for regions or applications 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. Also available in Stainless Steel and PVC
  • BASIC INSTALLATION: Each VAP/PA and VAP/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 VAP/PA and VAP/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
