Features & benefits

Elveflow is the only company offering cutting edge piezoelectric technology for flow control, and we developed a unique expertise. Our OB1–OEM system takes full advantage of our experience in the field of scientific research, but is also fitted to industrial constraints. Your system will benefit from our high-quality, robust and easy to integrate technology.

The performances of a cutting-edge research instrument

Piezoelectric technology
From the aerospace and automobile industry

Designed for integration

The OEM version of the flow controller is designed to be integrated in your complex systems. We have carefully thought of the mechanical and software design aspects in order to perform the integration.

The mechanical dimensions fit into twice as small dimensions as the standard version.
Thanks to the intuitive interface and the SDK libraries, the software helps you easily integrate the pressure controller. You can first control and use the pressure sensor with the ESI software. At a later stage, you can integrate instrumentation and use the OB1 flow controller with the available SDK libraries (C++, Python, MATLAB, LABVIEW). In addition to the ESI & SDKs, you can control the OB1 from any system (Mac, Linux, Arduino, Raspberry Pi, PLC) thanks to its new serial communication protocol.

Highly customizable

The pressure controller can be customized to fit your needs. Contact us so that we can provide you with the best product for your needs.

Highly customizable: 2-channels, 4-channels, 8-channels, 16-channels, 32-channels and 64 channels (more on demand).
Each pressure outlet can be set with a specific maximum pressure range: (200 mbar, 2 bar, 8 bar, -900mb/+1bar)
Each channel can be coupled with an additional flow meter

ESI is Elveflow’s more advanced software interface, built to make every experimenter’s life better. It is perfectly adapted from simple setups control to very advanced setups and workflows automation. It integrates several modules that make time-consuming and painful tasks so simple. It comes with SDK libraries (C++, Python, MATLAB, LabVIEW) to control the Elveflow system from with own code.
