The hydrodynamic optimized impeller is driven reliably even at low flow rates. Also under the highest loads it has enough reserve to detect even flow rate peaks. The specially enhanced bearing of the impeller causes low friction and guarantees a long service lifetime of the meter. The robust copper-glass-register is non-diffusive and protected against condensation. It also works reliably under the hardest conditions (e.g. in flooded pits or shafts).
The WSD is optimally prepared for remote reading. Retrofitting of electronic communication modules (EDC radio, EDC M-Bus, EDC pulse) and conventional Reed sensors is possible at any time and without violating the calibration seal.
