Abstract: 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, and of a battery-wifi-logger module. In this paper, we present the deployment of this UB-SediFlow during sediment managing operations. The UB-Sediflow was installed on a floating board. In parallel, another team collected SPM reference samples to qualify UB-SediFlow. Postprocessing analysis over a large frequency range gave quality data and this campaign showed an easy deployable instrument allowing real time data visualization.
