FEW400 – Electromagnetic flowmeter AquaMaster

FEW400AquaMaster Reduced Bore, battery operated, Electromagnetic Flowmeter. Allows highest levels of measurement accuracy in even the remotest of locations.


Key values for users:

  • 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 ‘single box’ DMA solution – combining flow, pressure and data-logging
  • Have greatest confidence in your billing based on highest accuracy with 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 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 smart phone / tablet app
  • Lowest total cost of ownership (TOTEX) over 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 size: 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)
