Design and layout
Rotary piston gas meters are manufactured for pressure stages pmax 10 bar, 16 bar. The pressurized parts within the gas meter are made of nodular cast iron. Up to size G 1000 the rotors are made of anodized light alloy, above G 1000 they are made of grey cast iron. The anodizing layer achieves a considerably higher resistance to wear of the piston surface.
