i_Flux water meter

i_Flux is an electronic residential single-jet water meter equipped with a radio module, which allows to read data remotely.


  • Remote reading of systems without the necessity to enter individual flats
  • Elimination of human errors taking place during manual reading
  • Internal memory storing up to 18 historical monthly readings
  • Fully reliable data reading
  • Leakage monitoring
  • Easy to integrate with existing AMR solutions

Safety is emphasized

The i_Flux water meter is equipped with internal systems detecting and registering reverse flow, maximum flow, external magnetic field manipulation attempt and physical tampering attempts. In case of such an event, the system generates logs in the appropriate error registers, which are then transmitted via radio directly to the administrator system.

Wireless M-Bus / OMS

The communication is based on the Open Metering System Standard (OMS). This standard is the only system definition in Europe which incorporates all media systems (water, heat, electricity, gas). OMS was developed by the industry to guarantee a future-proof communication standard and interoperability between all products on the market.

OMS products are offered by numerous manufacturers and can be combined easily.
