IoT Impulse reading typical use:

  • power, water, gas, heat or similar consumption readings
  • consumption savings analysis
  • regular monthly proforma billing optimization
  • emergency signaling – sudden change in consumption may indicate a leakage

Application of utility reading SENSECOM-IM1, IM2 or IMD is suitable for monthly and more frequent readings (from 15-minutes to daily intervals) or irregular readings, eg. when the preset pulse volume is reached.


  • Primary inputS0 impulse reading from billing or secondary power-meter
    • S0 – galvanically separated by powered optron
    • Supports 2-level tariffs (by grounding to neutral wire)
  • Secondary input – potential-free impulse input (NC) for Water/Gas – meter

Additional and optional features:

  • DIN rail (width 3U)
  • Input for elektronical seal (type IMDS, IMDSB)
  • Backup default 1h or extended 24h by supercap 2F (type IMDB, IMDSB)
  • Linkable to repeater SENSECOM-WSH to SIGFOX within ~20m for hard-to-reach SIGFOX places (metal cabinets, shafts, basement, etc.)
  • Galvanic separation with with resistance to surge >4.5kV
  • Shock detection (accelerometer)


The SENSECOM-IM1 or IM2 is used for secondary reading from electricity meters, water meters or gas meters to obtain information for

The reading from the meters is carried out via the standard interface “S0”:

  • IM1 – direct (no galvanic separation)
  • IM2 – via build-in optron, not powered input


Additional features:

  • Distinguishes between 2 tariffs, if used
  • Optionally connected to power outage and/or flood sensor, event. electronic seal (type IM1S, IM2S)
  • IP20 with external sockets or with cable through the grommet, also available in IP65 cover (type IMH1, IMH2)
