Thank you for sharing this.
I am slow to understand your device. The picture shows the home-made meter very clear. There are three rings and a ball between 2 plexiglass panels. Am I ok?
However, where does the fuel enters and where gets out? I mean, how does fuel move the ball? Why there are three rings? By the way, I imagine the ball is a plastic one, very light. Please correct me if I am wrong.
Looking forward to your explanation...

The smaller the engine, the closer the fit between ball and groove. If a center bolt is needed an o-ring is used to seal it. Drill a hole in the center bolt if it is used for the outlet connection. The plastic BB toleranted both gasoline and diesel fuel. Type of plastics used would determine the temperature range. Use a light source and sensor to count the ball rotations. Your mileage may vary.
