ROUND DSV - CARBON STEEL: FOR MOST APPLICATIONS

The Powder Coated Carbon 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 Carbon Steel DSV is specifically designed for installation within round ducts where temperatures do not exceed 400 degrees F and can be equipped with either Anodized Aluminum pitots or Stainless Steel pitots. The result, when coupled with any DP or Multivariable Transmitter, is a very accurate Differential Pressure based flow measurement.

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.
