AquaMaster4 - High-performance electromagnetic flowmeter for potable water distribution networks, revenue metering, and irrigation applications

The purpose of a potable water distribution network is to supply users with water with adequate pressure under various loading conditions. Water utilities strive to operate this process through a model that is sustainable to nature (i.e. water as a resource) and the financials of their business. However, networks are facing growing challenges (growing water scarcity, pressure on operational costs, water leakages, and waste) that could be mitigated with accurate metering solutions. The AquaMaster4 is the ideal flowmeter for potable water distribution networks and the high-tech response to the global need for water crisis mitigation and adaptation. It is the world's first self-verifying flowmeter which allows the integrity of the meter to be self-checked every 30 minutes and ensures meters are accurate and reliable. Using readily available standard lithium cells, the AquaMaster4 can be operated for over 10 years, and the transmitter can be powered by a range of green energy sources.

Key features

  • Unrivalled accuracy up to ±0.2% of reading ±0.5 mm/s (whichever is greater) across a wide flow range up to R1000
  • Estimated 11 kg CO2-eq
  • Expected lifetime of 15 years, batteries replacement after 10 years. Modular system easy to repair and unit entirely recyclable


  • Less than 8 months payback time
  • Affordable solution (price range: $1800 and $2000 for a standard size needed in a water distribution network) based on the size of installed flowmeter and project requirements
  • Helps detect leakages promptly which can reduce water waste of up to 11,400 litres per month on an average District Metering Area, reducing the financial losses for the customer by ~300K$ per month
