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.

A method of automatically calibrating a liquid treatment system in a seed treater, the method comprising:
- pumping a seed treatment liquid using a seed treater pump;
- receiving the seed treatment liquid in a container downstream;
- 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.
