| Datasheet

Application:

Domestic water meter


Features:
  • Modular multi-jet domestic meter with inductive scanning (without magnetic influence)
  • System capability, with standard applicable pulse output 1 l/pulse (inductive). CORONA MWI can be externed in any way - with IZAR RADIO COMPACT 868 I (radio module) or IZAR PULSE I (pulse transmitter)
  • 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
  • Strainer insert in inlet connection for cleaning without damaging the seal
  • Capable of withstanding any load for a short time
  • Fine adjustment by regulating plug
