The detailed visualization of velocity and acoustic turbidity profiles inside the liquid help to better understand the flow in many applications and setups. Here are some examples of applications, sorted by theme: wastewater, rivers, laboratory setups and processes applications.

Easy to install, the UB-Flow profiler is particularly well suited for field measurements. In rivers, it allows the measurement of both velocity and acoustic turbidity (which is directly linked to the suspended sediment concentration) profiles.
Velocity and acoustic turbidity field measurement with UB-Flow profiler allows a better understanding of sewer networks. Robust and autonomous, the UB-Flow profiler allows extensive measurements in sewage. When installed on the floor of the pipe, it measures the flow velocity at different levels without mechanical moving parts and with no risk of catching the transported waste.
During heavy rains, part of the wastewater can be discharged into the environment (sea, river) without any treatment. At the same time, various studies (e.g. Mallin and al. 2006) show that urban effluents contribute significantly to the deterioration of the quality of aquatic environments that have a direct impact on biodiversity and water activities.
The knowledge of the behavior of sewer networks and facilities allows a better sizing of those and therefore contributes to a reduction on their overall impact on the environment. In a similar way, the active management of the network (real-time control to avoid discharges), based on a reliable and accurate metrology, can significantly reduce pollution. In any cases, a better understanding of the hydraulic behavior allows a suitable management of these networks.

Our Ultrasonic Velocity Profiling (UVP) has a wide range of applications in Fluid Mechanics and Fluid Engineering, especially in laboratory setups.
Typical laboratory applications are:
- liquid metal flows,
- multi-phase flows,
- rheological properties of flowing food suspensions,
- physical scale models (rivers, lakes, channels, flow around a bridge, harbor, bay),
- and many more …
Our profiling technique is non intrusive, thus allowing to measure away from the transducer (probe). It works with both transparent and opaque liquids, as ultrasound waves can go through. It gives a spatio-temporal view of velocity and acoustic turbidity information.
The UB-Lab profiler (UVP) allows accurate velocity profiles measurements on laboratory setups and physical scale models, such as high resolution velocity profiling in oil, in a food processing pipe.
Localized sand patterns downstream from a vertical cylinder
The UB-Lab profiler used for the results of following paper: A. Auzerais, A. Jarno, A. Ezersky and F. Marin, Formation of localized sand patterns downstream from a vertical cylinder under steady flows: Experimental and theoretical study, PHYSICAL REVIEW E 94, 052903 (2016), and referenced as a high resolution ADCP.
Monitoring processes is important to ensure a good product quality. The modern industry, especially the 4.0 industry, aims to integrate more and more automated measurement on the production line.
Controlling the quality of a product in a process is not convenient to perform with the so called “off-line” techniques, as a sample needs to be collected and analysed. Measuring directly on the production line presents many advantages:
- the process flow is not disturbed or interrupted
- changes in product quality can be detected quickly, thus limiting product loss
- no sample collection is required
- the product is analysed under the process condition without a preparation delay.
Ubertone’s technology offers the ability to monitor different physical parameters which provide information on the structural change induced by a wide variety of processes. These physical parameters are the fluid viscosity, the speed of sound in the fluid and the shape of the velocity profile.
In-line rheometry with UB-Lab profiler allows an advanced knowledge of the product quality, which needs to be controlled in many food processes. For example, a real-time, accurate and non-invasive viscosity measurement based on UB-Lab has been developed.
