UB-Lab product family - Versatile ultrasonic profilers

UB-Lab profilers allow 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

The compact and splash-proof (IP65) enclosure of the UB-Labs is 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 dynamic web interface and integrate 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 devices 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. You can then, depending on your network configuration, connect to your device through WiFi.

The UB-Labs are declines in 3 versions:

The standard UB-Lab and the UB-Lab X8 allow to measure with respectively up to 2 and up to 8 transducers 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). The standard UB-Lab and the UB-Lab X8 are able to drive several transducers in a large frequency range (from 50 kHz to 9.4 MHz, > 800 kHz for velocity measurements) and it can therefore be adapted to many kinds of liquids and particles.

Like the UB-Flow profilers, those UB-Labs give 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 or four transducers, they can be used as a high resolution 2-3C ADCP (average velocity vectors).

The UB-Lab 2C can be equipped with 1 emitting transducer and 2 couples of receiving transducers. The multi-bistatic technique provides an instantaneous two component (2C) velocity vector measurement along a single beam (1D profile) at a high spatial and temporal resolution. This technique is also known as ADVP (Acoustic Doppler Velocity Profiler).

High resolution velocity profile in a pipe filled with sunflower oil

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

In-line rheometry in food processes

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.


Thesis presentation in ETH Zürich, UVP technique for food production and digestion processes

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

UB-Lab installation

You will find here how to install the UB-Lab from UBERTONE. The UB-Lab communication and powering go through a POE cable and supply.

Overall presentation - UB-Lab User Interface

You will find here how to start the graphical user interface of the UB-Lab from UBERTONE. It is an embedded web interface. And you will get an overview of this interface.

Note: it is almost the same interface for the UB-Flow.
