For some applications in both the industrial and energy sectors, the conditions are too harsh or the environment is too unforgiving for standard air flow measurement devices. Eastern Instruments has designed some specialty air flow measurement devices that can make accurate air flow measurement even in the harshest and most unforgiving conditions. Look no further than the VAP3® Heated Pitot which can accurately measure air flow down to -22o F without freezing over or frosting. The Heated Pitot is perfect for areas near cooling towers or duct work that is located in extremely cold environments.
Features & 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.
- 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.
- Independent 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.
