ABE’s Darr and McNaull awarded patent for grain mass flow estimation method

Matt Darr, professor of agricultural and biosystems engineering, and Robert McNaull, program coordinator in agricultural and biosystems engineering, were awarded a patent for a new grain mass flow estimation technique.

From the patent abstract: “a method of calibrating a mass flow sensor while harvesting grain includes sensing an accumulated mass of a portion of grain within a grain tank with a first sensor. A mass flow rate sensor is calibrated based at least in part on a signal of the first sensor.”
