AquaMaster 3 is an electromagnetic flowmeter designed for remote water metering and irrigation applications. It offers a wide range of power supply options for cost-effective site preparation and energy usage. It has an optional built-in multi-sampling rate, pressure and flow data logger. It supports wireless communication via an optional built-in GSM modem, allowing remote access and download of logged data. The device is fully potted and has an IP68 electronic package, ensuring zero water ingress even during flood conditions. It is compatible with ABB's full range of industry-leading flow sensors. The product has a full range of approvals including MID, OIML R049, and NMI approval pending.
The AquaMaster 3 electromagnetic flowmeter from ABB is designed for remote water metering and irrigation applications, offering high‑precision measurement across a wide size range (15 mm to 600 mm). It supports reduced‑bore and full‑bore sensor constructions and integrates flow, pressure, and totalizer data in a single unit.
Key features include IP68 sealed housing, optional GSM modem for wireless data access, multiple power options (mains with super‑capacitor backup, battery, solar/wind), an on‑board high‑resolution logger with up to 732 days of memory, and tamper‑resistant MID‑approved connections. The transmitter can be mounted close‑coupled or remotely and is re‑programmable in the field.
