Abstract: Disclosed herein is a method of automatically calibrating a liquid treatment system in a seed treater. The method is performed by pumping a seed treatment liquid using a seed treater pump, receiving the seed treatment liquid in a container, detecting when a predetermined volume of seed treatment liquid has filled the container using a first level sensor and a second level sensor and automatically adjusting a flow rate of the liquid in response to a time required to fill the container. Adjusting the flow rate may be done by adjusting a speed of the pump.

Abstract: An atomizer mixing chamber for a seed treater has a body having first and second inlets for receiving first and second treatment fluids. The atomizer mixing chamber has a first stage cup for receiving and combining the first and second treatment fluids to provide a combined fluid, the first stage cup comprising a first set of holes through which the combined fluid flows. The atomizer also has a second stage cup below the first stage cup for receiving the combined fluid from the first stage cup, wherein the second stage cup further mixes the combined fluid to provide a mixed fluid and wherein the second stage cup comprises a second set of holes through which the mixed fluid flows. The atomizer mixing chamber may include a third stage cup below the second stage cup for receiving the mixed fluid and having a third set of holes through which the mixed fluid exits from the atomizer.

Abstract: A seed treater having an automatic calibration system comprises a pump for pumping a seed treatment liquid, a container downstream of the pump for receiving the seed treatment liquid from the pump, the container having a first level sensor and a second level sensor between which a predetermined volume is defined and for signalling when the predetermined volume of seed treatment liquid has filled the container, an applicator for applying the seed treatment to seeds and a controller for automatically adjusting a flow rate of the liquid in response to a time required to fill the container. Adjusting the flow rate may be done by adjusting a speed of the pump.
