I figure out how the hall effect flow sensor works.When the fuel flows through the field, the
(weakly
magnetic) molecules line up magnetically. As soon
as they leave the field, they probably tend to misalign
again. The faster it flows, the further it goes before
misaligning, and the higher magnetic field will be
detected by the sensor. You wouldn't even have to
cut a line to measure.
