<p>A gas meter diaphragm is formed from liquid injected silicone rubber, with an integral annular bead (124) that permits its attachment to a pan assembly (80) without retaining rings or adhesives. By using liquid injected silicone rubber, the diaphragm can be molded rather than cut from a material sheet, allowing the diaphragm to have integrally formed retaining rings (124, 120, 220) or other physical features (100) or other physical features (100) with varying thicknesses of material.</p> |
