Low cost capacity measuring display installed in a label that is attached to an opaque container to measure amount of contents therein. The indicator utilizes the weight of the opaque container in conjunction with a gel reservoir and capillary that is installed in a label. The label extends under the can subjecting the gel reservoir to pressure that results from the weight of the container rendering movement of gel in the capillary that with calibration is a direct representation of the amount of contents in the opaque container.
