Abstract
A presence sensor combined to a first storage carrier for detecting a presence of a second storage carrier. A load cell measures the weight of the material expelled from the first storage carrier. A scale controller in communication with the presence sensor responds to the presence of the second storage carrier by recording of the weight measurement from the load cell.
Claims19
A system for measuring a weight of material that is transferred from a first storage carrier to a second storage carrier, the system comprising:
- a presence sensor combined to the first storage carrier for detecting a presence of the second storage carrier;
- a load cell for measuring the weight of the material expelled from the first storage carrier;
- and
- a scale controller in communication with the presence sensor for responding to the presence of the second storage carrier by recording of the weight measurement from the load cell;
- wherein the scale controller is in communication with the presence sensor, wherein the scale controller receives from the presence sensor a presence signal representative of the presence of an object, wherein in response to the presence of the object the scale controller determines a beginning weight of the material, and wherein the scale controller receives from the presence sensor a second signal representative of the absence of the object, and wherein in response to the absence of the object the scale controller records an ending weight of the material;
- and
- wherein the scale controller initiates a tare command to begin weighing the material in response to receiving the first signal, and wherein the scale controller ends the tare command to end weighing the material in response to receiving the second signal, and wherein the object is considered to be the second storage carrier when a difference in weight is greater than a predetermined setpoint value.
A system for measuring a weight of material that is transferred from a first storage carrier to a second storage carrier, the system comprising:
- a presence sensor combined to the first storage carrier for detecting a presence of the second storage carrier;
- a load cell for measuring the weight of the material expelled from the first storage carrier;
- and
- a scale controller in communication with the presence sensor for responding to the presence of the second storage carrier by recording of the weight measurement from the load cell, wherein the scale controller further comprises of a gross weight memory buffer for storing at predetermined intervals a weight measured by the load cell.
A system for measuring a weight of material that is transferred from a first storage carrier to a second storage carrier, the system comprising:
- a presence sensor combined to the first storage carrier for detecting a presence of the second storage carrier;
- a load cell for measuring the weight of the material expelled from the first storage carrier;
- and
- a scale controller in communication with the presence sensor for responding to the presence of the second storage carrier by recording of the weight measurement from the load cell, wherein the scale controller is in communication with a position subsystem to receive a position subsystem input representative of a geo-location and associates the weight measurement from the load cell with a geo-location.
A method for measuring weight of material, the method comprising:
- monitoring with a scale controller in communication with a load cell on a first storage carrier a weight of material in the first storage carrier;
- detecting with a presence sensor a presence of an object;
- entering a tare mode of the scale controller when the presence sensor detects the object;
- defining a beginning weighing for the tare mode;
- ending the tare mode of the scale controller upon detection of an absence of the object;
- and
- determining a tare weight record corresponding to an amount of material unloaded from the first storage carrier.
