ROUND DSV - STAINLESS STEEL: FOR HIGH TEMPERATURE APPLICATIONS

The Stainless Steel DSV is a flanged duct section which contains both straightening vanes for profiling turbulent air, as well as an array of flow measurement pitots. The DSV offers a similar accuracy as the VAP Pitot with the added benefit of being extremely easy to install. The round Stainless Steel DSV is specifically designed for installation within round ducts where temperatures can reach up to 900 degrees F. At these high temperatures the DSV is typically equipped with Stainless Steel pitots, but Anodized Aluminum pitots are also available. The result, when coupled with any DP or Multivariable Transmitter, is a very accurate Differential Pressure based flow measurement for ducts with high temperature air flow.

When mounted in SA (Superior Accuracy) mode, all of the models mentioned above will accurately measure the flow of relatively clean air through nearly any duct. While positioning the High Port so that it faces into the air stream (shown below) makes the measurement more accurate, it also limits the use of SA mode to particulate-free air. Mounted in SA mode, VAP pitots provide an accurate differential pressure output that allows for precise air flow measurement and control of your process to within +/-0.50% accuracy when calibrated.
