Domestic water meter


  • Modular compact multi-jet domestic meter with inductive scanning (without magnetic influence)
  • Housing and screw head made of composite are confirm with the Drinking water Ordinance
  • Resistant against dirt and aggressive water
  • System capability, with standard applicable pulse output 1 l/pulse (inductive). CORONA MCI can be externed in any way - with IZAR RADIO COMPACT 868 I (radio module) or IZAR PULSE I (pulse transmitter)
  • Mounting position: horizontal (R 40 - 160), rising pipe / downpipe (R 40)
  • Extremely low pressure loss and considerably extended measuring range
  • Records very small amounts of water consumption
  • Maximum long-term accuracy and absolutely corrosion-resistant
  • Measuring data better than specified by calibration regulations
  • Capable of withstanding any load for a short time
  • Outlet prepared for installing a non-return valve (DVGW approved)
