The Digmesa Flow Sensor FF was developed with the requirements of German draft beer systems in mind. It can be opened without any tools for easy cleaning. The version with a jewel bearing allows the mounting position to be chosen freely. Moreover, with the optional integrated foam probe, it measures only the actual amount of liquid that has been transferred. This prevents errors caused by carbonated gas when the line is empty. Thanks to the low-friction ruby bearing it is also suitable for dairy products.
