Mechanical water metering device

The mechanical water meter range of B Meters includes single-jet and multi-jet mechanical meters, magnetic or mechanical transmission types, suitable for residential as well as light commercial contexts. These water meters cover nominal sizes DN15 (½″) and DN20 (¾″) and handle both cold water (up to 50 °C) and hot water (up to 90 °C). All models feature dry-dial direct reading with multi-digit counters, threaded end connections compliant with EN ISO 228-1, and are certified according to the MID directive (e.g. for the GSD series) ensuring regulatory compliance and measurement accuracy. Typical flow rate ranges see permanent flow (Q₃) between 1.6 and 4.0 m³/h, maximum flow (Q₄) up to 5.0 m³/h, minimum detectable flows down to 0.05 L, and maximum operating pressure of 16 bar. In many models the dial is rotatable 360°, facilitating reading regardless of installation orientation. Moreover, some meters are pre-equipped to integrate M-BUS, wireless M-BUS or LoRa telemetry modules, enabling retrofit to automated remote-reading (AMR) systems in the future
