Abstract

A wireless metered fluid dispenser brings discrete fluid dispense events inside of a fluid management system. The wireless metered fluid dispenser allows a customer to visually confirm the fluid being dispensed and provides automatic tracking of the fluid dispense event within a wireless tracking system. A volumetric flowmeter attached to the bottom of a container or funnel tracks the amount of fluid dispensed when pouring from a container. The volumetric meter is wirelessly connected to a computer system for the transmission of data, for the purpose of centralized control and billing.

Claims

1. A handheld fluid meter comprising:

a fluid reservoir;

a valve attached to the fluid reservoir, the valve configured to control a flow of fluid out of the fluid reservoir; and

a flowmeter attached to the valve and disposed within the flow of fluid out of the valve, the flowmeter configured to measure a volumetric flow of the fluid through the meter and configured to wirelessly communicate the volumetric flow.

2. The handheld fluid meter of claim 1, wherein the fluid reservoir is removably attached to the valve.

3. The handheld fluid meter of claim 2, wherein the fluid reservoir comprises a funnel.

4. The handheld fluid meter of claim 2, wherein the fluid reservoir comprises a container prefilled with a known volume of fluid.

5. The handheld fluid meter of claim 1, wherein the valve comprises:

a valve mechanism; and

a valve trigger configured to be manually displaced to mechanically open the valve.

6. The handheld fluid meter of claim 1, wherein the valve includes a handle extending between the fluid reservoir and the flowmeter, the handle configured to be manipulated by a hand of a user.

7. The handheld fluid meter of claim 1, wherein the flowmeter comprises:

a volumetric meter configured to receive the fluid flow and to measure a volumetric flow; and

a communication module configured to wirelessly communicate the volumetric flow.

8. The handheld fluid meter of claim 7, wherein the communication module comprises a transceiver configured to both send and receive signals.

9. The handheld fluid meter of claim 7, wherein the volumetric meter is a positive displacement meter.

10. The handheld fluid meter of claim 7, wherein the flow meter further comprises a user interface.

11. The handheld fluid meter of claim 1, further comprising:

a nozzle extending from the flowmeter, the nozzle configured to route the fluid exiting the flowmeter.

12. A fluid management system comprising:

a fluid management computer comprising;

a processor; and

a memory encoded with instructions that, when executed by the processor, causes the processor to track and record a characteristic of a fluid being dispensed by one of a plurality of fluid dispensing components;

wherein at least one of the plurality of fluid dispensing components is a handheld fluid meter, the handheld fluid meter comprising;

a fluid reservoir;

a valve attached to the fluid reservoir, the valve configured to control a flow of fluid out of the fluid reservoir; and

a flowmeter attached to the valve and disposed within the flow of fluid out of the valve, the flowmeter configured to measure a volumetric flow of the fluid through the flowmeter and configured to wirelessly communicate the volumetric flow to the fluid management computer.

13. The fluid management system of claim 12, further comprising:

a transceiver configured to communicate with the fluid management computer via a wired connection and further configured to communicate with the handheld fluid meter via a wireless connection.

14. The fluid management system of claim 12, wherein the handheld fluid meter further comprises:

a communication module configured to send signals to the fluid management computer and to receive signals from the fluid management computer.

15. The fluid management system of claim 12, wherein the handheld fluid meter further comprises a user interface.

16. The fluid management system of claim 12, wherein the valve comprises:

a valve mechanism; and

a valve trigger configured to be manually displaced to mechanically open the valve.

17. The fluid management system of claim 12, wherein the flowmeter comprises:

a volumetric flow meter configured to receive the fluid flow and to measure a volumetric flow; and

a communication module configured to receive the volumetric flow from the volumetric flow meter and to wirelessly communicate the volumetric flow.

18. The fluid management system of claim 12, wherein the handheld fluid meter is gravity fed.

19. A method of tracking discrete fluid dispense events, the method comprising:

generating a work order associated with a discrete fluid dispense event;

dispensing the fluid according to the work order through a handheld fluid meter and from a container mounted on the handheld fluid meter;

generating a volumetric flow count of the fluid with the handheld fluid meter and wirelessly communicating the volumetric flow count to a fluid management computer with the handheld fluid meter.

20. A handheld fluid meter comprising:

a fluid reservoir comprising;

a neck; and

a cone-shaped body extending between the neck and a mouth, the cone-shaped body configured to route a fluid received through the mouth to the neck;

a valve attached to the fluid reservoir, the valve comprising;

a body extending between a first end and a second end, the first end connected to the neck of the fluid reservoir, the body including a handle portion configured to be manipulated by a hand of a user;

a valve member disposed within the body downstream of the first end, the valve member movable between an open position where fluid can flow through the valve member and a closed position where the fluid is prevented from flowing through the valve member; and

a trigger connected to the valve member and configured to actuate the valve member between the open position and the closed position; and

a flowmeter attached to the second end of the body downstream of the valve member, the flowmeter configured to measure a volumetric flow of the fluid through the meter and configured to wirelessly communicate the volumetric flow.
