20100077852	GAS METERING DIAPHRAGM - A diaphragm for use in a gas meter that includes an expansion section having a series of convolutions. During repeated use of the diaphragm, the expansion section flexes to allow the center section of the diaphragm and the attached diaphragm disk to move between a retracted position and extended position. The convolutions formed in the expansion section include a series of curved peaks and curved troughs joined by web sections. The multiple convolutions in the expansion section allows for more consistent and repeatable movement and volume displacement of the diaphragm between the extended and retracted positions. The action of the convolutions also contributes to extended life by eliminating wrinkling of the diaphragm material.	04-01-2010
