Different\n dimensions and materials allows to find the proper solution for every installation. A button valve\n type ME can be installed to prevent damages due to pressure surges.\n\n\n\nFeatures\n These pressure gauges are available with display dimension Ø63, Ø80 and Ø100. The\n connection is radial with male thread ¼” for Ø63, 3/8” for Ø80 and ½” for Ø100.\n\n Manometers are capsule types for pressure till 600 mbar, for higher pressure they have a\n Bourdon tube.\n\n They are designed in compliance with EN 837-1 and 3.\n\n The accuracy is ± 1,6% of full scale.\n\n They are suitable for ambient temperature -20/+60°C. If temperature of process medium is\n higher, proper devices shall be used to cool it before reaching the instrument (e.g. dissipators,\n capillaries).\n\n Continuous operating pressure can be max 75% of full scale.\n\n ME valve is a push-button valve which applies pressure to gauge only when it is pushed, in\n normal condition manometer is relieved of pressure. The installation of this valve extends life of\n pressure gauge and reduces possibilities of wrong reading (e.g. in case of dirty the pressure\n gauge can block in a position different from actual pressure).\n\n Suitable for air and non-aggressive gaseous fuels (families 1-2-3 EN437). Special versions are\n available for use with aggressive gases (e.g. biogas).\n\n This figure shows an example of typical installation in combination with other Elektrogas\n devices.\n\n\n 1 Ball valve VSG\n 2 Filter FG\n 3 Pressure regulator R\n 4 Tightness control LD\n 5 Min.
