New Flow Conditioner Removes Swirl For Accurate Mag Meter Measurement

The Vortab Company offers Vortab Elbow Flow Conditioner that eliminates the problem by removing swirl and asymmetric velocity profiles caused by pumps placed too close to the meter. This helps Wastewater treatment engineers find room for the recommended straight pipe run needed by electromagnetic flow meters in sewage lift stations.

San Marcos/California – To provide accurate and repeatable flow measurement, electromagnetic and other types of flow metering technologies 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 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-degree angle tab-type Vortab Elbow Flow Conditioner eliminates the pipe cost and technician labor for the 5 to 10 upstream and 3 to 5 downstream pipe diameters required by mag meters.

The Vortab Elbow was developed using the same tab-type flow conditioning technology as the straight run Vortab Flow Conditioners. Furthermore, it isolates the flow irregularities and conditions the flow stream into a swirl-free and symmetrical velocity profile. Swirl reduction and velocity profile correction occur naturally in long lengths of straight pipe due to diffusion and turbulent mixing. Vortab’s anti-swirl and inclined vortex generating profile correction tabs, projecting from the inside pipe surface, generate vortices that accelerate these natural pipe effects to create a uniform, non swirling, symmetrical flow profile in a much shorter section of pipe.
