During initial use, flow rate readings at multiple insertion depths can be obtained and averaged, allowing the user to determine a final installation depth that provides a reading close to the average flow in the duct.How It works:The measurement is made using the time-tested technol-ogy of Rheotherm thermal flow meters. The Rheovec sensor head is used on an insertion probe when the installation involves a duct that has little or no straight-run or flow straightening. The Rheovec head features a unique honeycomb structure around the probe tips that eliminates inaccuracies due to the off- axis velocities in the poorly conditioned flow stream. This allows more accurate measurement of the actual gas transport in the duct.These flow sensors typically come with Rheotherm Model 210 electronics for advanced signal processing, output signal and optional displays. See Bulletin M210 for further details.The problem:Flow rates in large air and gas ducts are notoriously difficult to reliably measure, particularly when there is limited room upstream for adequate straight-run or flow conditioning. Single point measure-ments can be noisy and inaccurate. Averaging multiple point measurements may help, but can be costly. The solution:Intek Inc.’s answer combines reliable Rheotherm flow metering technology with the unique Rheovec™ sensor head to improve repeatability and accuracy in difficult duct flows. The Rheovec head enables extraction of the actual velocity transport vector to give a more accurate reading of the total mass or volume flow rate.Other sensor details:• Line sizes: 4” and larger• Line connection: 4” flange (plate flange for low pressure or a higher pressure rated flange.)• Service: air and most other gases• Wetted surface: stainless steel (other materials available)• Hazardous service options: Yes.
