    Components

    GTA produces the high-precision rotating components inside many of Europe's gas meters - and supplies OEM-quality spare parts for installed bases of all major meter brands.

    ISO 9001
    Overview

    Precision-machined gears, cartridges and OEM spares - micron tolerances.

    From its Someren workshop, GTA precision-machines oval gears, rotor cartridges and other moving components to micron tolerances. Every part is 100% inspected on dedicated coordinate-measuring machines and supplied with full material certificates.

    Beyond OEM manufacturing, GTA holds inventory and tooling for spare parts across the major rotary and turbine meter brands - letting operators recondition existing meters quickly instead of replacing them, dramatically reducing lifecycle cost and lead time.
