Patent ID: 7007557

Claim:
An impact flow scale comprising: a first tube, disposed substantially vertically; a second tube, disposed with a downward inclination and having an inlet at an upper end thereof and a lower end of the second tube connected to the first tube, wherein the first and second tubes permit material communication therebetween; an impact plate; mounting means including a blade-like portion for hingedly suspending the impact plate at or near an upper end of the first tube such that the impact plate extends within the first tube; a material flow path defined from the second tube through the first tube, wherein the impact plate is adjustably positioned in the material flow path such that materials moving along the material flow path are capable of contacting the impact plate; and sensing means disposed outside the first tube, the sensing means being operably connected to the impact plate thus permitting detection of a horizontal force component generated as materials move along the material flow path.
