Bulk Water Meters WPD / WPHD 50mm to 500mm

Woltman meter with impeller axis arranged in parallel to the flow direction

The bulk water meter WPD / WPHD is used to record high flows in drinking water distribution and in industry, with low pressure loss and a predominantly constant flow profile at the same time.

The meter is equipped with a 6-roller dry dial register (IP68) and a modulator disc. This enables electronic, reaction-free scanning and is the basis for remote reading of the meter data via radio with LoRaWAN® or wM-Bus. A combined M-Bus / pulse module is also possible.

A mechanical pulser can also be connected in parallel.
