摘要 |
A gas meter includes a housing made of thermoplastic material having an inside wall defining two measuring chambers and a deformable membrane disposed between the two measuring chambers. The deformable membrane is formed from a film of thermoplastic elastomer material bonded to a synthetic fiber sheet. The periphery of the membrane is hot-welded to the wall between the two measuring chambers to form a gas-tight seal between the chambers. A mechanical drive train includes at least one lever having a hinged portion made from a thermoplastic material which is hot-welded to the middle of the membrane. The train drives a mechanical distributor disposed outside the housing. |
