It’s designed for advanced teaching and research with our Emriver models.
Using an open-source Arduino hardware-software interface, the Alix controller allows precise control of water flow. It also meters and displays flow rate, shows accumulated run time and flow, and automatically runs hydrographs.
The controller is back-compatible with all our Em2 models. It’s an extra on our new Em2 and Em3 models, and costs US$650.
The hardware and software are open source, and we hope to see users hack away. Its USB port allows easy connection to other computers.
Students could, for example, do real-time plotting of hydrographs as they run, coupled with time-lapse photography of channel changes in the model.
Development of this instrument turned out to be much more time-consuming and expensive than we planned.
