Patent ID: 11252855

Abstract:
A seed treatment applicator for applying a liquid seed treatment to an agricultural seed within a treatment chamber. A multi-port valve allows a first liquid source and a second liquid source to be fluidly connected to the multi-port valve. Multiple liquid sources may contain the same liquid treatment, mixed differently to have different densities. A liquid pump, such as a static rate pump, is fluidly connected downstream of the multi-port valve or directly connected to a liquid source. A modular control stick comprises a frame mounted to the treatment chamber, a mass flow meter mounted to the frame and fluidly connected downstream of the liquid pump and configured to generate a measured mass flow signal relative to a real time mass flow rate of the liquid seed treatment; and a flow meter transmitter operably connected to the mass flow meter and configured to generate a switch signal when comparison of the measured mass flow signal deviates from a reference value corresponding to a desired flow rate.
