Operating principle

The gas flowing through the meter sets a turbine wheel in motion. The number of revolutions of the wheel is proportional to the volume that has passed through the meter. The volume is registered by either a mechanical (QA) or an electronic (QAe) totalizer in the meter index.

Self-lubricating bearings ensure that the meter operates without the need for any regular maintenance. The metering principle is proven over decades also in fiscal applications. Design, materials and assembly process meet the highest standards.
