Abstract

A flow sensor apparatus for monitoring a directed stream of an agricultural product from an application port of a supply tube. The directed stream has a target directed portion and an off-target portion. A sensor housing includes a conical flow receiving element and a sensor body. The receiving element has an inlet orifice at a first end and a receiving element outlet at a second end. The first end is smaller than the second end. The sensor body has a sensor inlet end positioned to receive a target directed portion of the directed stream from the receiving element outlet of the conical flow receiving element wherein an off-target portion of the directed stream is not sensed. The sensor housing and sensor element are positioned external to the application port and thus positioned to provide measurement, targeting, and timing of the agricultural product.

First claim

What is claimed is:

1. A flow sensor apparatus for monitoring a directed stream of an agricultural product from an application port at an end of a supply tube, said directed stream having a target directed portion and an off-target portion, said flow sensor apparatus, comprising:
a sensor housing, comprising:
a) a conical flow receiving element having an inlet orifice at a first end and a receiving element outlet at a second end, said first end being smaller than said second end,

said inlet orifice being sized by selected operational characteristics of the directed stream and by a target area; and,
b) a sensor body having a sensor inlet end positioned to receive the target directed portion of the directed stream from said receiving element outlet of said conical flow receiving element, wherein the off-target portion of the directed stream is not sensed; and,

a sensor element positioned within said sensor housing, wherein said sensor housing and said sensor element are positioned external to said application port and thus positioned to provide measurement, targeting, and timing of the agricultural product.

2. The apparatus of claim 1 wherein said selected operational characteristics include: flow rate, flow pattern, and target size.

3. The apparatus of claim 1 wherein a measured flow rate is in a range of between about 0.5 fluid oz to 1 gallon per linear acre.

4. The apparatus of claim 1 wherein an operator is informed if the agricultural product is not applied in a position relative to seed being dispensed from a planter.

5. The apparatus of claim 1 wherein an operator is informed when a system-synchronized input is operating as intended and a synchronized pulse of crop input is being placed in proximity with individually planted seeds to deliver a desired biologic effect.

6. The apparatus of claim 1 wherein an operator is informed when a system-synchronized input is pulsing as intended, but a synchronized pulse of crop input is being placed in proximity with individually planted seeds, such that a desired biologic effect will not be realized.

7. The apparatus of claim 1 wherein an operator is informed when a system-synchronized input is pulsing as intended, providing an indication that a synchronized pulse of crop input is not being placed in proximity with individually planted seeds, to deliver a desired effect.

8. A method for monitoring a directed stream of an agricultural product from an application port at an end of a supply tube, said directed stream having a target directed portion and an off-target portion, the method comprising:
a) providing a flow sensor apparatus, comprising:
a sensor housing, comprising:
i. a conical flow receiving element having an inlet orifice at a first end and a receiving element outlet at a second end, said first end being smaller than said second end, said inlet orifice being sized by selected operational characteristics of the directed stream and by a target area; and,
ii. a sensor body having a sensor inlet end positioned to receive a target directed portion of the directed stream from said receiving element outlet of said conical flow receiving element, wherein the off-target portion of the directed stream is not sensed; and,

a sensor element positioned within said sensor housing; and,

b) directing the directed stream toward said flow sensor apparatus, wherein said sensor housing and said sensor element are positioned external to said application port and thus positioned to provide measurement, targeting, and timing of the agricultural product.

9. The method of claim 8 wherein said selected operational characteristics include: flow rate, flow pattern, and target size.

10. The method of claim 8 wherein a measured flow rate is in a range of between about 0.5 fluid oz to 1 gallon per linear acre.

11. The method of claim 8 wherein an operator is informed if the agricultural product is not applied in a proper position relative to seed being dispensed from a planter.

12. The method of claim 8 wherein an operator is informed when a system-synchronized input is operating as intended and a synchronized pulse of crop input is being placed in proximity with individually planted seeds to deliver a desired biologic effect.

13. The method of claim 8 wherein an operator is informed when a system-synchronized input is pulsing as intended, but a synchronized pulse of crop input is being placed in proximity with individually planted seeds, such that a desired biologic effect will not be realized.

14. The method of claim 8 wherein an operator is informed when a system-synchronized input is pulsing as intended, providing an indication that a synchronized pulse of crop input is not being placed in proximity with individually planted seeds, to deliver a desired effect.
