We develop a new flow meter with the help of CFD modelling

We worked with acoustic flow measurement systems developer – HydroVision GmbH (Hydrovision) – to develop a new acoustic flow meter. We used Computational Fluid Dynamics (CFD) modelling studies to develop this product. It provides users flexibility with pipe flow control and facilitates financial savings as well.

Placing a flow meter close to a flow obstruction in a pipe (such as downstream of an elbow or T-junction) often results in inaccurate flow rate measurements. Unlike a straight pipe, these areas of pipes have more complex shapes, resulting in high errors. As such, the placement of flow meter devices is currently restricted to positions with an undisturbed flow field. However, such positions can be difficult to find.

Our experienced simulation specialists used CFD to assess and analyse various kinds of disturbed flow fields. In so doing, they helped develop the new flow meter – a device capable of accounting for these disturbed flow fields and using acoustic signals is not the special thing.

This device does not require a long, straight section of pipe to ascertain flow measurements. This allows for precise measurements at previously impossible pipe locations. Additionally, it is customisable. This allows for real-time processing and can be tailored to meet individual needs in terms of accuracy and special flow conditions.
