Abstract

Systems and methods for transporting and/or sensing mass of industrially useful material to identify inventory, mass or volumetric delivery rates. A load measuring apparatus comprising a framework and at least one load sensors coupled to the framework is disclosed. The load sensor senses a load applied to the framework.

Claims

1. A load measuring apparatus comprising:

a vehicle;

a weighing platform coupled to the vehicle;

a transportable container removably securable to the weighing platform;

a first lever arm defined by a first end and a second end;

a second lever arm defined by a first end and a second end;

a first support foot on the first lever arm and a second support foot on the second lever arm; and

a load sensor;

wherein the weighing platform is transportable by the vehicle;

wherein the weighing platform is operable to weigh the transportable container;

wherein the first ends of the first and the second lever arms are coupled to the weighing platform and the second ends of the first and the second lever arms are coupled to the load sensor;

wherein the first support foot is located between the first end of the first lever arm and the second end of the first lever arm; and

wherein the second support foot is located between the first end of the second lever arm and the second end of the second lever arm.

2. The apparatus of claim 1, wherein a position of the first support foot on the first lever arm and a position of the second support foot on the second lever arm are adjustable.

3. The apparatus of claim 1, further comprising a first pinned support on the first lever arm and a second pinned support on the second lever arm.

4. The apparatus of claim 3, wherein the position of the first pinned support on the first lever arm and the position of the second pinned support on the second lever arm are adjustable.

5. The apparatus of claim 1, wherein the first lever arm and the second lever arm are coupled to the weighing platform through a pivotal connection.

6. The apparatus of claim 1, wherein the weighing platform, the first lever arm and the second lever arm form a single piece.

7. The apparatus of claim 1, wherein a distance from the first end of the first lever arm to the load sensor is substantially equal to a distance from the first end of the second lever arm to the load sensor.

8. The apparatus of claim 1, further comprising one of a temperature sensor, an angle sensor, a fluid density sensor or a fluid level sensor coupled to one of the weighing platform, the first lever arm or the second lever arm.

9. The apparatus of claim 1, wherein the load sensor is an electronic load cell.

10. The apparatus of claim 1, further comprising a locking mechanism coupled to the load sensor, wherein the locking mechanism isolates the load sensor from the first lever arm and the second lever arm.

11. The apparatus of claim 1, further comprising a computer system for analyzing data obtained from the load sensor.

12. A load measuring apparatus comprising:

a vehicle;

a weighing platform coupled to the vehicle; and

a transportable container removably securable to the weighing platform;

wherein the weighing platform is hinged at a first end;

a load sensor coupled to the weighing platform;

a support foot coupled to the load sensor; and

a lifting device coupled to the weighing platform, wherein the lifting device protects the load sensor from shock loads;

wherein the load sensor senses a load applied to the weighing platform by the transportable container.

13. The apparatus of claim 12, wherein the load measuring apparatus rests on a roading foot when lifted by the lifting device.

14. The apparatus of claim 12, wherein the load sensor is positioned at a second end of the weighing platform.

15. The apparatus of claim 12, wherein the load sensor is an electronic load cell.

16. A method of measuring a load comprising:

coupling a weighing platform to a vehicle;

removably securing a transportable container to the weighing platform;

coupling the weighing platform at a first end to a first torque sensor;

providing support to a first side of the weighing platform;

applying a load to a second side of the weighing platform;

using the first torque sensor reading to determine a value of the load applied to the weighing platform by the transportable container;

coupling the weighing platform at a second end to a second torque sensor;

coupling a first lever arm to the first torque sensor;

coupling a second lever arm to the second torque sensor;

providing support to the first lever arm and the second lever arm; and

determining a value of the load applied to the weighing platform by the transportable container from a sum of the torque sensed by the first torque sensor and the torque sensed by the second torque sensor.
