This revisin is issued with respect t the extensin f the meter range t G-value 6 (G6). 1.1 Essential parts Descriptin Dcumentatin Remarks Cnstructin Descriptin 276/ Assembley drawings 276/2-002 Diaphragm /2-004 distributr distributr supprt / /2-006 Material synthetic rubber, manufacturer EFFBE France. 1.2 Essential characteristics See EEC pattern apprval nr. E276 Revisin 2 and the characteristics mentined belw: - maximum p max : 0,5 bar 1. Essential shapes 1..1 The gas meter, clearly legible, at least cntains the data as mentined in the EEC regulatins n gas meters (see example n page 7 and 8) Sealing : see chapter Cnditinal parts Husing The gas meter has a husing, which has sufficient tensile strength. The cver is made f steel sheet, the lwer and upper case are cnnected with each ther by a clamp. The cunter case is als cnnected t the upper case by screws. Examples f the husing are stated n page nrs., 4 and Transmissin The transmissin between the measuring part and the cunter is executed via a fixed mechanical cupling r a magnetic cupling Cunter The indicatin takes place in m, by at least 5 drums befre the cmma and drums after the cmma. On page nr an example f the cunter is presented. The cunter is adjustable by using the adjustment screw, see the adjustment instructins n page nr
