Overview
New markets, and thus new requirements, initiated the development of the IRM-3 series. Revolutionary in the design of rotary gas meters are the square shaped impellers or rotors, resulting in a compact, robust meter with a high turn down ratio and with a minimum of maintenance required. The combination of the compact design and the dual rotor design enabled flow ranges up to 1600 m³/h and high performance up to 16 bar.
