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:
