VAP APPLICATIONS: ROUND DUCT INSTALLATIONS
VAP Pitots have a unique Velocity Averaging and Parallel Plate proprietary design. When inserted in air flow ducts, the VAP Pitots provide an accurate, differential pressure output allowing for precise air flow measurement or control of your process. VAP Pitots are designed for Superior Accuracy (SA) for clean air applications or plug resistant (PA) for heavy particulate-laden applications. The VAP Pitots can be installed in existing or new ducts or incorporated into flow-conditioning devices, such as the High Beta, designed for short duct run applications with turbulent air flow or to obtain optimal accuracy. The VAP Pitot can be manufactured out of Anodized Aluminum, Stainless Steel or PVC for accuracy in nearly any application.
VAP APPLICATIONS: ROUND DUCTS
VAP APPLICATIONS: ROUND DUCTS
The VAP Pitot comes in a variety of models, each designed to accurately measure the flow of air or gas under particular circumstances. Whether measuring clean air, or air that is particulate-laden, the VAP pitot delivers an extremely accurate differential pressure output. The standard VAP pitot is constructed out of Anodized Aluminum for maximum durability, however, both PVC and Stainless Steel versions are available for applications where the air/gas being measured may be caustic to Aluminum, or where the temperature within the duct may reach up to 900o F. The VAP Pitot is typically installed via ports that are welded to the exterior of duct work. The pitots are then bolted to these ports for easy installation.
VAP PITOT INSERTION PORTS
An insertion port is typically welded to the exterior of a duct and pitots are then bolted to the insertion port. A curved radius allow the port to be easily mounted to round ducts.
VAP PITOT BULL NOSE PORTS
A Bull Nose receiver and port is typically used on round ducts over 34" in diameter and helps to stabilize and support the pitot inside the duct. The Bull Nose Receiver is welded to the exterior of the duct just like the insertion port.

SPECIALIZED PITOT VERSIONS
ANODIZED ALUMINUM - MOST APPLICATIONS
The VAP Anodized Aluminum Pitot is designed as an extremely accurate, low-cost solution for air flow measurement in clean or particulate-laden air streams. The VAP Aluminum Pitot is perfect for air streams with temperatures under 700 degrees F (371 degrees C).
STAINLESS STEEL - HIGH TEMPERATURES
For high temperature applications in which air or gas temperatures can reach 900 degree F (482 degrees C) Stainless Steel VAP Pitots are available. The Stainless Steel pitot is also great for applications in which caustic materials are being measured.
PVC - CAUSTIC MATERIALS
The VAP3® PVC Pitot is designed for extremely accurate differential pressure (or flow pressure) of caustic gases. The VAP PVC pitot is constructed entirely out of PVC and is corrosive resist against a variety of gases. The pitots can be used in either clean air or air streams with particulate in them.
VAP-XL - VERY LARGE DUCTS
The VAP XL Pitot is a larger version of the standard VAP Pitot that is specially designed to span the large distances of very large ducts. Just as the standard VAP pitot, the VAP-XL offers extremely accurate differential pressure (or flow pressure) of air or gas in ducts. The VAP-XL pitot is constructed entirely out of Anodized Aluminum and can be used in either clean air or air streams with particulate in them.
HEATED PITOT - FREEZING TEMPERATURES
The Heated Pitot from Eastern Instruments utilizes the original VAP Pitot technology by providing an accurate differential pressure output, that allows for precise air flow measurement and control of your process. By incorporating integral controlled heaters with our pitots, they can continue to function in conditions where ice build-up is present.
