<p>A gauge and a method for assessing the content of releasable gas in a bottle of compressed or liquified gas, in which the weight of the content is assessed by determining the force required to cause the bottle to pivot about a point on its lower periphery. The gauge has a platform (16) pivoted about a horizontal edge on a frame (10, 12) and is spring-urged upwardly. This causes the bottle to pivot about a diametrically opposed-point on the bottle rim periphery, provided the spring (32) exerts a sufficient force. The platform (16) is connected to a pointer (25), which sweeps across a scale provided on the frame 10. A screw-threaded adjuster (33, 34) is arranged to preload the spring (32), thereby to allow alignment of the pointer (25) with a "full" marking on the scale when the gauge is first positioned beneath a full gas bottle; thereafter the remaining content can be assessed by the instantaneous indication.</p> |
