Jual BULK Water Meter ZENNER WPD / WPHD

Description

Type Woltman parallel: WPD (DN 50 – 150), WPHD (DN 200 – 300)

WPD / WPHD is a woltman bulk water meter with parallel turbine shaft.

The ZENNER Bulk water meter WPD / WPHD is specially constructed for the measuring of high flow rates with a mainly constant flow rate profile. Due to the  robust design, WPD / WPHD can cover a wide measuring range and provide accurate measuring results over a long period. So it covers almost all measuring tasks in the drinking water supply and distribution.

The housing of the WPD / WPHD was flow-optimized. The mesuring insert was newly constructed as a replacable metrological unit according to european MID. In combination with an up-to-date bearing of the impeller a good linearity and long-term stability of the error curve can be achieved. 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  WPD / WPHD 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.
