The turbine gas meter  measures the quantity of gas basing on the flow principle. The gas flows through an integrated flow 

conditioner, which distributes the flow proportionally in the annular slot and guides it to the turbine wheel. The wheel is driven
by the gas flow, and the angular velocity of the rotation is proportional to the gas flow rate.
The energy consumption, perceived as pressure loss, is reduced to absolute feasible minimum due to the application of the flow
conditioner, highest precision ball barings, most accurate tolerances of all measuring parts and their proper alignement.

The rotary motion of the turbine wheel is transferred mechanically by gear wheels, and the incorporated gas tight and hermetic magnetic coupling,
to the index unit, which is mounted on the top of the body, and shows the operating volume on the totalizer

The basic components  turbine gas meter are as follows:
pressure resistant  meter  bodyinlet flow conditionermeasuring cartridge with  the turbine wheel magnetic coupling as the  transferring  element
between  measuring  cartridge and the index  lubricating  system  (some meters are  provided with self  lubricating  bearings)
