Gas Measurement in Short Pipe Runs
Measurement accuracy in smaller installations with severe flow disturbances with no flow conditioner
8-path Ultrasonic specifically designed for short run applications
Reduced capex often means that pipeline measurement skids must occupy a smaller footprint, decreasing the installation costs of these sites. These smaller installations often cause installation effects in ultrasonic measurement since most ultrasonic meters require long pipe runs to ensure accurate measurement. The Rosemount 3418, however, is an 8-path meter specifically designed for short run applications with severe flow disturbances that result from these installation effects. By leveraging our T-200 transducer in an 8-path design, the Rosemount 3418 can be installed in pipe runs as short as 5D upstream and 3D downstream with no flow conditioner, thereby reducing costs and ensuring the greatest measurement accuracy.

Product Solutions
The new Rosemount 3418 8-path ultrasonic flow meter crafted, developed, and designed by Emerson, offers the highest accuracy and best in class performance coupled with the same high functionality required by sophisticated fiscal measurement users. The 3418 combines the power of two interlocked 4-path British Gas design meters in one flow meter body. The second set of chords is the mirror image of the first, which allows the meter to cancel out the effects of swirl and cross flow. The 3418 Flow Meter boasts a 0.5 OIML accuracy class and requires only five diameters of straight run and no flow conditioner.
- No flow conditioner reduces compression and pumping costs and eliminates maintenance due to blockages
- High rangeability of >100:1 ensures fewer meter runs smaller line sizes and lower capital costs
- 3410 Series Electronics provide fast sampling, an expandable electronics platform and an archive data log containing pressure, temperature and gas composition information which allows the meter to act as a redundant flow computer
