Abstract
An apparatus, system and method for measuring quantity of a material are disclosed. One or more sensors are used to measure the quantity of the material are measured and error causing parameters are also measured. Error causing parameters are processed by executing one or more correction methodologies to determine a correction output. The quantity of the material is measured by using the correction output. One or values associated with the quantity of the material are measured and displayed. The one or more values are transmitted to a server and informative messages are received from the server.
Claims14
An apparatus comprising:
- a load-bearing platform for holding a container with material;
- a first sensor coupled to the load-bearing platform, wherein the first sensor is configured to generate readings that vary with a load placed on the load-bearing platform;
- a second sensor configured to measure an ambient condition, the second sensor built into the load bearing platform;
- a communications port;
- a memory operable to store a set of computer instructions;
- and
- a processor operable to execute the set of computer instructions to:
- receive a first reading from the first sensor;
- receive a second reading from the second sensor;
- determine a first quantity of a first material that has been placed on the load-bearing platform based on the first reading and based on the second reading;
- and
- cause an indication of the first quantity to be transmitted to an external entity via the communications port.

An apparatus comprising:
- a load-bearing platform for holding a container with material;
- a first sensor coupled to the load-bearing platform, wherein the first sensor is configured to generate readings that vary with a load placed on the load-bearing platform:
- a second sensor configured to measure an ambient condition:
- a communications port;
- a memory operable to store a set of computer instructions, the memory also storing a Calibration Temperature;
- and
- a processor operable to execute the set of computer instructions to:
- receive a first reading from the first sensor;
- receive a second reading from the second sensor, wherein the second reading is a temperature:
- determine a tentative quantity of a first material that has been placed on the load-bearing platform based on the first reading;
- determine, based on the second reading, an error using the formula 0.25*Full-Scale*(Current Temperature−Calibration Temperature)/10;
- adjust the tentative quantity by the amount of the error in order to arrive at a first quantity of the first material that has been placed on the load-bearing platform;
- and
- cause an indication of the first quantity to be transmitted to an external entity via the communications port.
