Abstract
An example support for a fluid container is described, comprising a bracket comprising a U-shaped cross section and a strain gauge attached on a web of the U-shaped cross section of the bracket, between a mounting portion for attaching the bracket to a printing apparatus and a bearing portion for attaching a fluid container to the bracket. An example method for determining the amount of fluid in a container is also described, comprising measuring with a strain gauge a strain occurring at the web of a U-shaped bracket, the U-shaped bracket having a wing for attachment to a printing apparatus and a wing for carrying a fluid container; and determining the amount of fluid in the fluid container based on the measured strain.IPC Classes ?
