Ultrasonic apartment / domestic water meter

The IUWS ultrasonic water meter guarantees reliable recording of the meter data for individual consumption billing in the residential or domestic water sector.

The IUWS is equipped with a 9-digit LCD display. The integrated radio interface is preset at the factory to wireless M-Bus (OMS) or LoRaWAN®. If required, this can also be changed at a later date. All variants are approved for any installation and are therefore also available in the usual lengths for riser and downpipe installation. A head-down mounting is also possible. 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).
