DSV - DUCT SECTION VAP

The DSV allows for simple installation of velocity averaging VAP insertion pitots into any duct
Eastern Instruments' DSV - Duct Section VAP retains all of the air flow measurement features and capabilities of the VAP Pitot, while offering the additional feature of being exceedingly easy to order and install. The DSV is a round, spooled section of duct that contains an array of VAP Pitots along with straightening vanes that help channel air flow through the flow measurement section of the DSV. Just as stand-alone VAP Pitot arrays, the DSV can be installed into new or existing ducts for both clean air applications and for particulate-laden applications. Each pitot contained within the DSV has multiple total and static sensing ports that are specifically located in order to provide a full traverse of the duct, thus eliminating the concern of measurement error due to highly random distributions of air. Utilization of VAP Pitot technology ensures that the DSV is an extremely accurate and convenient method of measuring air flow.


INTRODUCTION TO TECHNOLOGY



The DSV for simple installation of velocity averaging pitots in any duct


DSV - DUCT SECTION VAP

Whether installed in round ducts or rectangular ducts, the DSV consists of an array of pitots that is pre-mounted into a section of duct. The duct section typically contains flanges for easy installation and features straightening vanes which will assist in eliminating the effects of swirl on the flow measurement. The integral pitot array is tubed together and offers a single High and single Low port that will tube to the QVT transmitter as well as any other model DP or Multivariable Transmitter.


DSV CONFIGURATIONS

DSV - ROUND DUCTS



DSV Duct Section VAP Air Flow Measurement System with Integral Velocity Averaging Pitots for Round Ducts
The Round DSV comes in standard sizes ranging from 4" up to 36" in diameter and is offered in a variety of materials and pressure ratings that can accommodate even the most hostile air flow measurement environments. The DSV is also equipped with flanges on either side of the spooled duct section, allowing for easy installation upon arrival at your site. Most importantly, however, is the off-the-shelf design of the DSV that allow for minimal lead times from order to installation. The DSV can be used for either clean air or for particulate-laden air applications. The measurement pitots can either be manufactured out of Anodized Aluminum or Stainless Steel.
