Radial-blade turbine gas meter: a concept with many benefits
Monopipe adapter EAS§ Is a component of the pipeline§ Flange connection DN 50 – DN 100§ Thread connection G 1½” and G 2”§ For preparation of the measuring point the EAS can be
installed in advance with an over flow cap or lid capinto the pipeline.
Radial-blade turbine gas meter§ The gas meter to be built-in at need of measurement only§ Meter sizes G/Q 16 up to 40§ Measuring range of 3 up to 650 m3/h§ There is a solution for each demand
Over-run brake (option)§ Oppression of after-run error at intermittent operation
without restriction of the measuring range.

Radial-Blade Turbine Gas Meter: easy installation & maintenance
The separation of meter and EAS enables a stress-free meterinstallation.
The heavyweight monopipe adaptor EASremains in the pipeline.
Fitting position from horizontal to vertical.Four times 90° rotatable on the EAS.
Simple exchange of meter on the spot.
