VAP Insertion Pitot - High Heat Applications
Brand: Eastern InstrumentsThe VAP-SFS Insertion style pitot, when inserted into either new or existing duct work, will provide a differential pressure output that is equivalent to the flow within the duct.
The VAP-SFS Pitot is constructed out of 316 Stainless Steel and can be oriented for either clean air applications or for applications where the air contains particulate.
The Stainless Steel pitots offer accurate measurement for duct transporting high temperature air or gas.
These pitots are typically mounted via insertion ports that are welded to the exterior of the duct work, but they can also be directly mounted to the duct as well.
FeaturesTwo Unique Designs
- The VAP/PA Pitot is designed for particulate-laden applications. Can be placed in heavily particulate or condensate-laden environments while still measuring accurately and reliably without being prone to plugging.
- Ideally designed to provide accurate differential pressure outputs for precise air flow measurement in process applications, the VAP/SA is suitable for relatively clean process environments (such as clean flows or filtered gas streams), where high accuracy is required for measurement and control.
Accuracy
- Accuracy to within ±2% and repeatability to within ±0.1%, depending on upstream and downstream straight runs.
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.
In Duct Sensors are Passive
- There are no active, electronic components or moving parts that are installed within the air stream, therefore eliminating maintenance costs and ensuring reliability.
Engineered Solutions
- Heated Pitots, High Velocities, Large duct installations (VAP/XL Pitots (Up to 240 inches)), and much more to meet customer specific needs.
