Device for measuring the rate of flow of flowable products, particularly loose material

A device for measuring the rate of flow of a flowable material comprising means for containing a stream of flowable material, a balance beam adapted to extend into said container means, a measuring plate secured to said balance beam so as to be disposed in said stream of material flowing through said container means, said plate being mounted on said balance beam so that its measuring surface extends substantially parallel to the longitudinal axis of said balance beam, a housing mounted on said container means, said balance beam having an end portion extending into said housing, a pivot for said balance beam disposed in said housing, said pivot having a pivot axis extending in a first plane which is normal to a second plane containing the longitudinal axis of said balance beam in the position of equilibrium of said balance beam, and which first plane is parallel to a stationary centroidal axis of said stream of flowable material, and such pivot having its axis obliquely disposed relative to the intersection of said first and second planes, and a mechanism disposed in said housing operatively associated with said balance beam to act on said balance beam in opposition to the deflecting forces acting on said measuring plate.
