Sensus HRI Pulse Sensor

HRI (high resolution interface) is a universal sensor which is compatible with a wide range of meters, including single-jet, multi-jet and piston meters with dry-dial and semi-dry registers in glass-copper or plastic housing. HRI can be retrofitted on all Sensus meters since 2008 preequipped with an HRI modulator.

HRI is available in two versions:

  • The HRI-A PulseUnit is a high resolution pulser which detects the flow direction.
  • The HRI-B DataUnit is an electronic register with a data interface which supports both hardwired M-Bus systems and battery-driven MiniBus devices such as mobile meter reading systems. The HRI-B can alternatively be used as a pulse type with configurable pulse output.
