Venturi pipe for flow measurements

As we were going through the brewery’s hose system and replacing the sanitary valves, we also found the need to upgrade our flowmeter to a larger size. We started from the same theory as the previous version but made it more robust and, most importantly, designed it for higher flows. With the old venturi pipe, the differential pressure sensor would have bottomed out due to significantly higher flows with the new hoses and valves.

We used Formlabs Rigid 10K resin for the pipe itself.
