Radial-Blade Turbine Gas Meter, a concept with many advantages
Radial-Blade
Turbine Gas Meter
Radial-Blade Turbine Gas Meter
■ The gas meters need not to be built-in until measurement is
required
■ Meter sizes G/Q 16 – 400
■ Measuring range: 3 – 650 m3/h
■ Four different pulse generators:
– 2 × NF (low frequent)
– MF (middle frequent)
– HF (high frequent)
■ There is a solution for every demand
Over-run brake (option)
Over-run brake
■ Suppression of the after-running error at intermittent operation
without restriction of the measuring range

Component of the pipeline
Flanged DN 50 – DN 100
Threaded G 1 1/2” and G 2”
In preparation of the measuring point the monopipe fitting can be
installed in advance in the pipeline with an overflow cap or lid cap
Installation and maintenance
■ Can be installed in any position from horizontal to vertical
■ Simple exchange of the meters on site. The heavyweight
monopipe adaptor remains in the pipeline
■ The disconnection of the meter and monopipe adaptor allows
a strain-free meter installation
