Abstract
A scale for determining a quantity of material in a container such as a keg. The scale may include a support member configured to be placed under a portion of the container, a display to indicate the quantity of material in the container, and a weight sensor positioned underneath the support member to determine the quantity of material in the container and to provide a signal to the display.
Claims21
A scale for determining a quantity of fluid in a container comprising:
- a support member configured to be placed under a portion of the container;
- a display to indicate the quantity of fluid in the container;
- a weight sensor positioned underneath the support member to determine the quantity of fluid in the container and to provide a signal to the display;
- and
- a calibration device to calibrate the weight sensor.
A scale for determining a quantity of fluid in a container comprising:
- a support member configured to be placed under a portion of the container;
- a display to indicate the quantity of fluid in the container;
- and
- a weight sensor positioned underneath the support member to determine the quantity of fluid in the container and to provide a signal to the display,
- wherein the weight sensor includes an electronic load cell.
A scale for determining a quantity of fluid in a container comprising:
- a support member configured to be placed under a portion of the container;
- a display to indicate the quantity of fluid in the container;
- and
- a weight sensor positioned underneath the support member to determine the quantity of fluid in the container and to provide a signal to the display,
- wherein the weight sensor wirelessly transmits information to the display.
A scale for determining a quantity of fluid within a keg comprising:
- a pad to contact a rim of the container wherein a surface area of the pad is smaller than a surface area of a bottom surface of the container;
- at least one raised portion on an end of the pad;
- a display to indicate a measurement of the quantity of material within the container;
- and
- a weight sensor positioned underneath the pad to determine the quantity of material within the container and to provide a signal to the display.
A scale for determining a quantity of material within a keg comprising:
- a housing;
- a lever arm having a first end connected to the housing and a second end free, the lever arm moveable between a first position and a second position wherein when the keg that is full of fluid is first placed on the scale, the lever arm is in the first position and as the fluid is gradually consumed from the keg, the lever arm gradually moves from the first position to the second position;
- a spring having a first end connected to the housing and a second end connected to the lever arm;
- a display having an empty indicator and a full indicator;
- and
- a display indicator attached to at least one of the lever arm or the spring capable of moving between the full indicator and the empty indicator in response to the lever arm moving from the first position to the second position.
A scale for determining a quantity of material within a keg comprising:
- a housing defining a cavity and having a first raised portion and a second raised portion;
- a load cell positioned within the cavity to determine the quantity of material within the keg;
- a pad positioned between the first raised portion and the second raised portion and on top of the load cell to contact a rim of the keg wherein a surface area of the pad is smaller than a surface area of a bottom surface of the keg;
- and
- a display to receive a signal from the load cell wherein the display contains at least one control device to calibrate the load cell when the container is empty and when the container is full.
