DSV - DUCT SECTION VAP
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. Like 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. Its use of VAP3® Pitot technology ensures that the DSV is an extremely accurate and convenient method of measuring air flow.
INTRODUCTION TO TECHNOLOGY
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 a single Low port that will tube to the
QVT transmitter as well as any other model DP or Multivariable Transmitter.
DSV - 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 allows 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 be manufactured out of either Anodized Aluminum or Stainless Steel.
DSV - RECTANGULAR DUCTS
The Square or Rectangular DSV can be manufactured in a variety of sizes to fit nearly any duct size 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 duct section, thus allowing for easy installation upon arrival at your site. The DSV can be used for either clean air or for particulate-laden air applications and the measurement probes can be manufactured out of Anodized Aluminum or Stainless Steel.
