Suspended Particulate Matter (SPM) measurements are a very important challenge of operational flow monitoring. The ANR project MESURE led to the development of a compact dual-frequency ABS prototype tested on a river. Following this research project, a compact commercial version was developed by Ubertone, composed of a hyperband acoustic module, an...

Measuring velocity profiles in turbulent flows has always been of great theoretical and practical interest. It allows the statistical characterisation of turbulence and better understanding of processes such as sediment motion, closely related to the flow turbulence. A full agreement on how turbulent flows are affected by presence of particles is y...

Through its hardware size, the installation and handling of UVPs was not convenient. Also the setup complexity limited the UVP technology to trained users or ultrasonic technology experts. In this extended abstract, we present the world's first handheld UVP, which simplifies its use on large setups and moving systems. The UB-Lab P has, through the...

This is the result of the post-processing of raw acoustic backscattered signal measured with the UB-SediFlow, an ABS by UBERTONE. It allows to get full concentration profiles over the whole river depth and to monitor concentration distribution evolution in time and space.

In the present paper, a data set of time-resolved two components velocity profile measurements under steady uniform turbulent rough clear water and sheet-flow are presented. The purpose of this campaign was to evaluate the performances of a commercial ADVP, the UB-Lab 2C from the company Ubertone, by comparing it to a well-established instrument, t...

In the present paper, new data set of co-located 2C velocity and sediment concentration time-resolved measurements under steady uniform turbulent rough clear water and sheet-flow, performed with an Acoustic Concentration and Velocity Profiler (ACVP) and a prototype for a commercial ADVP, the UB-MES, are presented. The flow regime for the measuremen...

Knowledge on Suspended Sediment Concentration (SSC) leads to a better understanding of sediment transport dynamics, which is of main interest to understand river geomorphology or handle the wastewater regulation and treatment. For this purpose, optical and acoustic turbidity are both used to monitor continuously the suspended solids content in wate...

The suspended sediment concentration (SSC) is a key element for water quality monitoring. Optical turbidity is already widely used as SSC indicator and acoustic backscattering devices are still under investigation. Recent observations on a wastewater network showed huge differences between the behaviour of optical and acoustic turbidity according t...

Ubertone has developed a new hardware for industrial and low power applications. This new development pushes further the technological limits of UVP to reach a lighter and smaller board. The electronics consumes less and powers up very quickly. The device communicates through the Modbus protocol over RS485. The comparison with a reference UVP prove...
