Abstract: The Application discloses an in-line, high capacity apparatus and method for measuring a flowable component, such as seed, grain or other material. The apparatus and method generally function by measuring the pressure applied to a rounded cap by the flowing material. In certain embodiments, the apparatus and method comprise a housing containing a sensing unit, with the housing further comprising a rounded cap in mechanical communication with a load cell. In certain exemplary embodiments, the apparatus and method also comprise a processor, wherein the sensing unit is in communication with the processor so as to measure the flow rate of material passed through the housing by measuring the pressure of the material on the rounded cap. In certain embodiments, the apparatus and method allow the user to regulate the flow rate.
