UB-Lab - The versatile ultrasonic profiler
The UB-Lab profiler allows accurate velocity profiles measurements from the laboratory flume to the industrial process.
- High spatial and temporal resolution
- Large transducer choice
- Fine frequency tuning
- Web interface
This technology is also known as UVP (Ultrasonic Velocity Profiling) or UDV (Ultrasonic Doppler Velocimetry).
The compact and splash-proof (IP65) enclosure of the UB-Lab is adapted to harsh environments. This scientific instrument is able to drive two transducers in a large frequency range (from 300 kHz to 9.4 MHz) and it can therefore be adapted to many kinds of liquids and particles.
Like the UB-Flow profiler, the UB-Lab gives access to the acoustic turbidity which allows the evaluation of Suspended Sediment Concentration (SSC). It can measure simultaneously velocity and acoustic turbidity profiles.
When equipped with two transducers, the UB-Lab can be used as a high resolution 2C ADCP.
This device can be used within a laboratory as well as in an industrial context (see application for in-line rheometry). It breaks new ground by offering the user new capabilities in the fields of fluid study and control.
The device is configured through a dynamic web interface and integrates an internal logger (3Go) which allows the storage of a large amount of data, enabling days or months of monitoring (depending on configuration).
Ethernet communication goes through RJ45 cable. The device can behave like a DHCP server when connected directly to the computer, or it can be connected to the network and behave like a DHCP client. You can then, depending on your network configuration, connect to the device through WiFi.

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.
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.
The oral examination of the PhD thesis of Damien Dufour took place on the 23rd Feb 2018 and symbolized the end of a 5 years’ work at the Food Process Engineering laboratory of ETH Zurich. The thesis is entitled “Ultrasound Doppler Flow Measurement in Food Production and Digestion Processes” and experimental data has been recorded by an UB-Lab from Ubertone. ... read more
