arrange for the grains to impact a vertical plate at a uniform velocity.

the magnitiude of the perpendicular force they impart on the on the plate is
directly proportional to the rate of flow

try googling for "grain flow sensor"

Do you wish to detect merely that the powder is flowing or to actually
measure the flow speed?
