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 due to the application of the flow conditioner, highest precision ball bearings, most accurate tolerances of all measuring parts and their proper alignment.
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 turbine wheel, as a standard is made of aluminum. This allows providing each CGT turbine gas meters with HF inductive pulse sensors. There are no extra costs due to the replacement of the turbine wheel.
