6. The gas meters during storing should be protected against direct atmospheric influence,and against humidity.7. Special care should be taken not to destroy leaden seals placed during legal calibration.IF THE SEALS ARE DAMAGED THE LEGAL CALIBRATION, AS WELL AS THEGUARANTEE, MAY BECOME INVALID.8. Lubrication of bearings during storing is not necessary.VI. INSTALLATION AND START-UPPrior to the installation of the gas meter check whether it has been selected properly, inaccordance with the operating parameters of the system. In particular, attention should be paidto the following information contained in the name plate:• maximum operating pressure [MPa], marked p max ,• maximum real flow [m 3 /h], marked Q max .• permissible operation position:- H horizontal (standard execution),- VD vertical; flow from top downwards (option – on request),- VU vertical; flow from bottom upwards (option – on request).It is permitted to operate the gas meter with flow bigger by 25% than the designedmaximum flow within maximum 30 minutes.The gas meter should not be installed in the lowest position of the installation as it is possibilethat condensate and other impurities may collect there.The turbine gas meters should be installed in closed compartments or under appropriateshields. It is not permitted to expose the gas meters to rain or snow falls, or pollution withother substances (e.g. dust).The gas meter should be installed in piping of the appropriate nominal diameter. Properalignment of the gas meter and pipe flanges should be secured, in accordance with appropriateregulations in the gas industry. The piping system should not exert pressure on the gas meterbigger than determined by the standard PN-EN 12261:2003. Especially dangerous are forcestransverse to the centre line of the gas meter. Gas meters with weight bigger than 50 kgshould be supported so as they do not weigh down the installation.When designing the place for the installation of the gas meter the dimensions given in Tables3a and 3b, and in Fig.14, may be useful.17
