The heart of a gas meter is the pair of diaphragms. The measuring has to occur with the same precision at -25oC as at +60oC. There is no material fatigue allowed for decades and also a change of the geometry of the diaphragms is not allowed.
Rubber covers with a thickness of 0.15 mm to 0.30 mm are manufactured with a thickness tolerance of only +/- 0.02 mm.
