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 malfunction. The standard VAP3® Pitot has a unique Velocity Averaging and Parallel Plate proprietary design. When inserted into air flow ducts, they provide an accurate, differential pressure output for precise air flow measurement or control of your process. The Heated Pitot utilizes this same VAP3® Pitot technology to deliver an extremely accurate differential pressure output. 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 & Benefits;
• Great for Freezing temperatures – The VAP3 can prevent freezing of the pitots down to -22o F , perfect for regions that routinely see freezing temperatures.
• Versatile Design – Due to the VAP3® Heated Pitot’s unique design, can be utilized in both clean air applications as well as in particulate-laden applications.
•Parallel Plate Cross Sectional Design – Minimizes turbulence at 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.
