Electronic water metering devices

The B Meters electronic and smart meter range (e.g. HYDROCAL-M4) is designed to meet the needs of modern water and energy metering in residential, multi-unit and light commercial buildings. The meters are available in nominal diameters DN15 (¾″) and DN20 (1″) and are engineered for compatibility with both hot and cold water networks, as thermal/energy meters with centralised heating/cooling systems. All models feature digital measurement sensors and direct reading via an 8-digit LCD display with icons, and the calculation unit can be rotated 360° to facilitate reading regardless of installation orientation. All models include integrated wireless data communication (Wireless M-BUS or LoRa), and can be retrofitted or equipped with wired communication modules (e.g. M-BUS with pulse inputs), enabling remote reading and integration into automated meter reading (AMR) or smart-metering systems. The nominal flow and performance parameters vary with model, but the design ensures reliable measurement accuracy (MID / EN standard compliance), ease of installation, and long-term robustness
