Electromagnetic Flowmeter AquaMaster FEW400


Key values for users:

  • The solution from the masters of flow measurement – in 1988, ABB invented and designed the world’s first battery-powered electromagnetic flowmeter for DMA (District Metered Area)
  • Invest smartly through a ‘single box’ DMA solution – combining flow, pressure, and data-logging
  • Have the greatest confidence in your billing based on the highest accuracy with the widest flow range revenue meter
  • Get early warnings for leaks or bursts and reduce NRW (Non-Revenue Water) – highest confidence in night line performance
  • Have the highest confidence in the wet calibration – our flow rigs are certified by various national independent accredited bodies/laboratories all linked by the ‘International Laboratory Accreditation Cooperation (ILAC)
  • Fit and flow with factory default settings. To customize minimal on-site configuration required with quick and easy configuration through ABB Velox mobile smartphone/tablet app
  • The lowest total cost of ownership (TOTEX) over the complete product lifecycleAquaMaster conforms to the latest international standards to meet increasing legislative demands for accurate flow metering. Its wide measuring range ensures peak daytime flows are accurately recorded and its exceptional low flow performance aids network leak detection.
  • Fit and flow for foolproof installation, all data is stored in the sensor to reduce on-site setup. AquaMaster’s unique sensor design conditions the flow profile resulting in excellent meter performance in poor hydraulic installation conditions.


  • Measurement parameters: flow rate, flow velocity, volume flow (forward, reserve, and net), and pressure (option)
  • Wide range of sensor styles and sizes: reduced bore DN40 to 600, full bore DN40 to 2400, and probe 300 to 1000 mm. Range up to R1000 and accuracy up to ±0.2% ±0.5mm/sec whichever is greater.
  • Power options: 10 years battery life, solar / wind renewable, and AC mains
  • Communication options: Pulse, Modbus, and Sensus with wireless interface to mobile smart phone/tablet
  • High and low flowrate alarms
  • Applicable for arduous applications: IP68 for submersion and up to 5m buriable
  • Verification: in situ diagnostics and self-checking capabilities
  • Backward compatible with legacy AquaMaster sensors
  • Drinking water certifications: WRAS, NSF, ACS, AS/NZS 4020
  • Metrological approvals: OIML R49 and MID MI-001 (pending)


Key benefits

  • Measure, log, and communicate with a single box and achieve more with less capital expenditure for your district-metered areas.
  • Increase billing confidence and deliver accurate bills for true consumption levels, not estimates.
  • Pave the way for easy operations and have peace of mind while the flowmeter maintains itself.
  • Reduce operational expenses and waste while controlling supply and demand more accurately.
  • Receive near real-time communication as the flowmeter reads and writes over the air.
