Here is the video of the project:
This project proposes to install a flowmeter between the beer barrel and the tap. Each time a beer is served the information is sent to Carriots. Then, all data is stored and pushed to external information systems to extract useful information by the smart Business Intelligence guys.

You can create a similar project using our tutorial on how to combine Arduino, Raspberry Pi, a flowmeter and Carriots to collect data: https://www.carriots.com/tutorials/Arduino_RPi_Carriots/flowmeter
This tutorial includes all the source code you need to create the project.
Enjoy it!
