Zenner - Model WPD / WPHD -Bulk Water Meters

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.

• For the measuring of high flow rates
• For horizontal or vertical installation
• For cold water up to 50° C

• Retrofittable with up to two reed-sensors
• Stationary GSM system

Serially equipped with communication interface for:

• Electronic pulser
• Wired M-bus
• Radio via wireless M-bus according to OMS (Open Metering System)
• Radio via LPWAN (LoRaWAN™, SIGFOX)
