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.
1 more element
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.
