UB-Lab product family - Versatile ultrasonic profilers
UB-Lab profilers allow accurate velocity profile measurements from the laboratory flume to the industrial process.
- High spatial and temporal resolution
- Large transducer choice
- Fine frequency tuning
- Web interface
The compact and splash-proof enclosures of the UB-Labs are adapted to harsh environments. These scientific instruments can be used within a laboratory as well as in an industrial context (see application for in-line rheometry). They break new ground by offering the user new capabilities in the fields of fluid study and control.
The devices are configured through a responsive web interface profiles can be visualized in real time. They integrate an internal logger which allows the storage of a large amount of data.
The UB-Lab UVPs work in monostatic modus, meaning the same transducer emits bursts and receives the corresponding echoes. This technology is also known as UVP (Ultrasonic Velocity Profiling) or UDV (Ultrasonic Doppler Velocimetry) and provides 1-component velocity profiles (projection on the transducer axis).
When equipped with two transducers, they can be used as a high resolution 2C ADCP.
Depending on the version, those instruments allow measuring with up to 8 transducers in monostatic modus and are able to drive several transducers in a large frequency range (from 25 kHz to 9.4 MHz). They can therefore be adapted to many kinds of liquids and particles.
They can simultaneously measure velocity and echo amplitude profiles.
They are declined in two groups:
- the UB-Lab P is a handheld profiler equipped with a Wifi connexion and an internal battery in a compact enclosure with two channels.
- the UB-Lab S4 can control four channels. Possible to manufacture solutions with more channels on request.
- the UB-Lab X2 and the UB-Lab X8 can measure with a very high time resolution (up to 100Hz). They have temperature inputs and even pressure inputs for the X8. And both integrate a raw echo signal output. Like the UB-Flow profiler, they give access to the acoustic turbidity which allows the evaluation of Suspended Sediment Concentration (SSC). They are connected through Ethernet and can behave like a DHCP server when connected directly to the computer, or they can be connected to the network and behave like a DHCP client.

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
