HEATED VELOCITY AVERAGING PITOT

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!



INTRODUCTION TO TECHNOLOGY





VAP HEATED PITOT WITH CONTROLLER

The Integral Heated Pitot can be installed in clean-air or particulate-laden applications, and will typically still retain the accuracy of our original VAP (±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.

HOW IT WORKS

The Heated Pitot comes either as an individual pitot, or an array of pitots, for larger ducts. Each Heated Pitot comes with an integral heating element that is maintained by a controller which is provided. The Heated Pitot Controller can control up to 4 pitots at once and will maintain the temperature of the heater element and thus the pitot, in order to prevent ice buildup on the ports which could diminish the ability of he pitot to accurately measure flow.



FEATURES AND BENEFITS

ACCURACY: Can be +/- 2.00% accuracy depending on upstream/downstream straight runs

CONSISTENCY: Maintains a pitot temperature of 50 F (10 C) per pitot

SAFETY: Over-temperature remote trip controller set to 176 F (80 C) to prevent over heating of pitot

FUNCTIONALITY: Prevents pitot freezing down to -22 F (-30 C)

OPTIMIZATION: Customizable pitot sizes in order to fit your duct configuration
