METHOD FOR MAKING MEMBRANE GAS METER

摘要

Method for making membrane gas meter at which point contact welding of holder with outer cover is performed over protective coating that is applied preliminarily to parts with galvanic method with following additional protection of welding points, one provides balance of needed amount of welding energy at ratio of height of boss of the holder to thickness of material of cover from 0.75 to 1.5, at membrane passing end positions one controls force of crank with equilibration at two sides within 20…90 grams.
