Vortab elbow flow conditioners

To provide accurate and repeatable flow measurement, electromagnetic and other types of flow metering technologies used in many plants require a specific amount of straight pipe run upstream and downstream from the installed location of the meter. The straight pipe runs create a swirl-free and symmetric velocity profile in the pipe that can be measured accurately over and over again.

The Vortab Company’s elbow flow conditioner nearly eliminates the flow meter upstream piping requirements by conditioning the flow stream into a flow regime, mimicking adequate straight run. In addition to conditioning the flow stream, the 90° angle tab-type Vortab elbow flow conditioner eliminates the pipe cost and technician labour for the 5 to 10 upstream and 3 to 5 downstream pipe diameters required by many types of flow metering technologies.

The Vortab Elbow was developed using the same tab-type flow conditioning technology as the straight run Vortab flow conditioners, which have been laboratory proven and successfully installed in hundreds of plants worldwide. To validate the Vortab elbow’s design, ball valves, gate valves, out-of-plane and in-plane elbows and swirl generators were installed at the immediate inlet of the Vortab elbow and tested in state-of-the-art gas and liquid calibration facilities.
