Woltman well water meter WBD

Well water meters are meters from type Woltman perpendicular with a special design of the housing.

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.
