Bulk water meter WPD/WPHD T90
The bulk water meter WPD/WPHD T90 is suitable for a medium temperature of up to max. 90 °C.
It can be used to record high flow rates in drinking water distribution and in industry, with low pressure loss and a mostly constant flow profile.
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. Factory tested according to MID specifications. All materials, which are used in the drinking water section, comply with the required standards, guidelines and the current German drinking water approval (other country-specific drinking water approvals on request).
