ULTRASONIC METER

Static ultrasonic water meter for accurate measuring and recording for all applications of water supply.

  • Ultrasonic water meter with long-term stability under difficult conditions (no measurement of air and insensitive against sedimentation)
  • Higher performance than class D requirements
  • Metrological class 2 and dynamic range up to R 400
  • Compliant with MID, OIML R49 and EN 14154
  • Mounting in any installation position, no calming sections required
  • Housing with thread connection lead-free brass
  • IP68 suitable for outdoor installations
  • Certified for drinking water (KTW and ACS)
  • Wired M-Bus, Radio OMS, Radio/L-Bus and Pulse interface available
  • Radio communication based on Open Metering telegram (OMS-Generation 3, Profile A, or OMS-Generation 4, Profile B, selectable)
  • Highest data security for AMR communication
  • Displaying of error- and alarm codes, including leakage detection
  • Battery lifetime up to 16 years
  • Data logging capabilities to record up to 1.024 daily values + 32 configurable values (hourly, daily, weekly, monthly) and an annual due date
