Flow Conditioning Improves Flow Measurement Accuracy and Reduces Process Plant Costs
The necessary addition of elbows, expansions or reductions, and/or or spiral piping in close proximity to instrumentation and other devices often further exacerbates the problem of inadequate pipe straight runs. Too much equipment, too little space and poor piping layouts all work together to alter the process media’s tangential, radial and axial velocity vectors. Flow disturbances then result, including swirl, jetting and velocity profile distortions.
The impact of flow disturbances on flow meters, pumps and other equipment can be significant. In the case of flow meters, irregular material flows adversely affect the accuracy and repeatability of many of the most popular flow sensing technologies: differential pressure, turbine, magnetic, thermal, ultrasonic and vortex shedding. Depending on the flow sensing technology, the straight pipe run requirements for flow meters varies—from 10 to 20 or more diameters Flow Disturbance Problems.
