ABSTRACT:
An impact flowmeter utilizes a part cylindrical impact plate mounted by a parallelogram strain gauge from the top of a cylindrical housing with which it is coaxial. Material to be metered enters the flowmeter through an inclined inlet tube so as to impact the inner surface of the impact plate, and the horizontal reaction force from the plate is measured by the strain gauge. The flowmeter is simple to construct and can be made very compact, while the cylindrical surfaces of the principal components minimizes disturbances of the flow of material through the unit and thus provides good linearity.
