The mechanical base water meter type EMS-ECO-WG-TWO-ONE-MODUMESS forms the stable basis for the M-Bus water meter EMS-ECO-WG-TWO-ONE-MODUMESS-MBUS
The mechanical single-jet residential water meter type EMS-ECO-WG-TWO-ONE-MODUMESS forms the stable and reliable basis for the electronic M-Bus water meter EMS-ETW-ECO-WG-TWO-ONE-MODUMESS-MBUS.
As a fully dry-running mechanical meter with magnetic coupling for transmitting the rotary motion, it ensures precise and durable water consumption measurement.
This fully dry-running design keeps the measuring mechanism completely isolated from the water flow. This guarantees not only an exceptionally long service life but also exceptionally high measurement accuracy.
Dry operation prevents deposits and ensures that the meter functions reliably under all conditions.
The advanced magnetic coupling principle enables precise and secure transmission of the rotary motion without water ever entering the metering area. This technology ensures high wear resistance.
The precise transmission of the rotary motion from the measuring mechanism to the counter via magnetic coupling guarantees reliable measurement results at all times.
Flexibility and versatility thanks to the EMS-ECO-WG-TWO-ONE-MODUMESS mechanical base water meter
The EMS-ECO-WG-TWO-ONE-MODUMESS mechanical water meter is ideal for the precise measurement of cold and hot drinking water. Thanks to its dry-running technology, it is suitable not only for private households but also for use in commercial buildings and industrial areas. With a wide range of models, the meter covers diverse requirements and offers a reliable solution for both small and large installations.
However, its true advantage lies in its flexibility: This meter forms the basis for expansion to modern remote reading and communication technologies.
With its robust construction and excellent measuring accuracy, the EMS-ECO-WG-TWO-ONE-MODUMESS not only provides a reliable foundation for daily operation but also allows for the easy integration of an M-Bus module.
This M-Bus module (model EMS-WMMBA1-N) is already factory-installed, parameterized, and sealed in the EMS-ECO-WG-TWO-ONE-MODUMESS-MBUS model.
This transforms the meter into a powerful component of a networked, digital meter reading system. This future-oriented solution enables efficient, error-free, and cost-effective recording of water consumption – whether for private households, commercial buildings, or industrial applications.
