Smart metering systems


A water metering system using M-Bus technology for residential water metering and data transmission.

HYDROLINK Line is the wired M-Bus implementation of the intelligent and remotely readable HYDROLINK Water Metering Systems. HYDROLINK Line consists of GSD-RFM water meters and a central unit. In addition to water meter counters, consumption readings can also be read from the HYDROLINK Online service. The cloud service is free of charge and includes automatic email reporting that can be activated if desired. The reports can be downloaded in different file formats, compatible with all property management programs (e.g., Visma, Tampuuri, Domus, Kupari).  

Residents can monitor their daily water consumption on the optional AD-2 Home Display or through the HYDROLINK Online Premium service, which can be used either online or with a phone application.
