IZAR PULSE i is a pulse emitter that can be clipped onto all the water meters of the Diehl Metering inductive modular range (Ti) making them communicative in a very easy way.
IZAR PULSE i generates pulses to manage the water volume and features fraud alarms. It can be connected to remote reading or consumption analysis systems.
IZAR PULSE i features a clamping ring for secured fixing and easy re-mounting on another meter.


  • Compatible with inductive modularity "Ti"
  • 3 and 4-wires versions available
  • Several configurations possible on request
  • Flow direction management
  • Tampering alarms
  • Open collector output
  • Available in dry-contact version, specific pulse weights and 3-output version
  • Up to 15 years lifetime
  • Operating principle

    IZAR PULSE i is a ring equipped with a sensor based on the inductive principle and with a specific electronic system that exploits the information to be transmitted in the form of an open-collector signal (polarised).
    The inductive system featured in IZAR PULSE i is actuated using a metal ½ disc located in the Diehl Metering modular register of the water meter.
