Abstract
Described herein are systems and devices for controlling and monitoring liquid applications of agricultural fields. In one embodiment, a flow device for controlling flow during an agricultural operation includes an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to an outlet passage. The flow device also includes a first passage that provides a first flow path from an inlet to at least one opening of the offset ball valve and second passage that provides a second flow path from the inlet to at least one opening of the offset ball valve.
Claims24
A flow device for controlling flow during an agricultural operation, comprising:
- An inlet;
- An outlet passage;
- an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to the outlet passage;
- a first passage to provide a first flow path from the inlet to at least one opening of the offset ball valve to the outlet passage;
- and
- a second passage to provide a second flow path from the inlet to at least one opening of the offset ball valve to the outlet passage.
6-8. (canceled)
A control and monitoring unit comprising:
- a valve having an opening for controlling flow of a liquid through the valve to an outlet;
- a first passage to provide a first flow path having a variable first flow rate from an inlet to the valve, the first passage includes a first flow meter to monitor flow of the liquid through the first passage;
- and
- a second passage to provide a second flow path having a variable second flow rate from the inlet to the valve, the second passage includes a second flow meter to monitor flow of the liquid through the second passage.

(canceled)
An implement, comprising:
- at least one tank for storing a liquid to be applied to a field;
- a plurality of row units each having a flow device that includes an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to an outlet passage for an application of the liquid to the field;
- and
- a pump coupled to the plurality of row units, the pump to control a flow of the liquid to the plurality of flow devices.
