Abstract

An example container for collecting bulk material dispensed from a meter during a calibration operation may include a canister comprising an open end to receive bulk material, a coupler configured to releasably couple to a meter, and at least one weight sensor extending between the enclosure and the coupler. The weight sensor may be configured to detect weight of the bulk material deposited into the enclosure via the open end.

First claim

What is claimed is:

1 . A container for collecting bulk material dispensed from a meter during a calibration operation, the container comprising:
a canister comprising an open end to receive bulk material; a coupler configured to releasably couple to a meter; and at least one weight sensor extending between the canister and the coupler, the weight sensor configured to detect weight of the bulk material deposited into the canister via the open end, wherein the canister is moveable relative to the coupler, and further comprising a guide coupled to the coupler, the guide defining a direction of movement of the canister relative to the coupler.

2 . The container of claim 1 , further comprising a stop that limits movement of the canister relative to the coupler.

3 . The container of claim 2 , wherein the guide defines vertical movement of the canister relative to the coupler such that the canister is vertically movable relative to the coupler.

4 . The container of claim 1 , wherein the coupler comprises a flange extending along at least a portion of the open end.

5 . The container of claim 1 , further comprising a cavity formed between the coupler and the canister.

6 . The container of claim 5 , wherein the at least one weight sensor is disposed in the cavity.

7 . The container of claim 1 , wherein the weight sensor comprises a first end and a second end, wherein the first end of the weight sensor is connected to the coupler and the second end is connected to the canister.

8 . The container of claim 7 , wherein the first end and the second end of the weight sensor are laterally offset from each other.

9 . The container of claim 1 , further comprising an electrical connector, wherein the electrical connector is configured to communicate weight information associated with a weight of bulk material dispensed into the canister.

10 . The container of claim 1 , further comprising a memory, communicably coupled to the at least one weight sensor, that stores weight information associated with a weight of the bulk material dispensed into the canister.

11 . The container of claim 1 , wherein the meter comprises a plurality of meters, wherein the canister comprises a plurality of compartments, and wherein each compartment is positioned to receive bulk material from a corresponding meter of the plurality of meters.

12 . A method for providing weight information of a bulk material dispensed by a meter into and sensed by a container coupled to the meter, the method comprising:
coupling a container comprising a weight sensor to a meter such that bulk material dispensed from the meter is received into the container; sensing a weight of the dispensed bulk material received into the container with the weight sensor; and communicating the sensed weight of the bulk material, via electronic signals, to an electronic controller of the meter, wherein the container comprises a canister and a coupler moveable relative to the canister and wherein sensing a weight of the dispensed bulk material received into the container with the weight sensor comprises sensing an amount of displacement of the canister relative to the coupler in response to the bulk material received into the canister.

13 . The method of claim 12 , further comprising calibrating, with the electronic controller, the meter using the sensed weight of the bulk material.

14 . The method of claim 12 , wherein communicating the sensed weight of the bulk material, via electronic signals, to an electronic controller of the meter comprises transmitting the sensed weight with an electrical connector of the container.

15 . The method of claim 12 , wherein communicating the sensed weight of the bulk material, via electronic signals, to an electronic controller of the meter comprises wirelessly transmitting the sensed weight.

16 . The method of claim 12 , wherein the meter comprises an air seeder meter.

17 . The method of claim 12 , wherein the weight sensor comprises a load cell.

18 . The method of claim 12 , further comprising limiting an amount of displacement of the canister relative to the coupler.

19 . A computer-implemented method performed by one or more processors for automatically calibrating a bulk material meter, the method comprising the following operations:
operating a bulk material meter to dispense an amount of bulk material into a container coupled to the meter, the container comprising an electronic weight sensor; sensing, with the electronic weight sensor, a weight of the bulk material received into the container; transmitting the sensed weight of the bulk material to an electronic controller of the meter; and calibrating the meter using the sensed weight of the bulk material, wherein the container comprises:
a coupler; and
a canister movably coupled to the coupler, and
wherein sensing, with an electronic weight sensor, a weight of the bulk material received into the container comprises sensing an amount of displacement of the canister relative to the coupler.

20 . The computer-implemented method of claim 19 , wherein operating a bulk material meter to dispense an amount of bulk material into a container coupled to the meter comprises operating the meter a selected number of cycles or for a selected period of time.

21 . The computer-implemented method of claim 19 , wherein transmitting the sensed weight of the bulk material to an electronic controller of the meter comprises transmitting the sensed weight of the bulk material via a wired electrical connection between the electronic weight sensor and the electronic controller of the meter.

22 . The computer-implemented method of claim of claim 21 , wherein the wired electrical connection comprises an electrical connector of the container.

23 . The computer-implemented method of claim 19 , wherein transmitting the sensed weight of the bulk material to an electronic controller of the meter comprises transmitting the sensed weight of the bulk material via a wireless electrical connection between the electronic weight sensor and the electronic controller of the meter.

24 . The computer-implemented method of claim 19 , wherein calibrating the meter using the sensed weight of the bulk material comprises altering a rate of operation of the meter.

25 . The computer-implemented method of claim 19 , wherein the meter is a volumetric meter.

26 . The computer-implemented method of claim 19 , wherein the electronic weight sensor comprises a plurality of electronic weight sensors and wherein sensing, with an electronic weight sensor, a weight of the bulk material received into the container comprises sensing a weight of the bulk material with the plurality of electronic weight sensors.

27 . The computer-implemented method of claim 26 , wherein sensing a weight of the bulk material with the plurality of electronic weight sensors comprises summing the sensed weights sensed by the plurality of electronic weight sensors.
