NB-IoT Smart Remote Reading Water Meter

The Smart Remote Reading water meter adopts the advanced NB IoT(Internet of Things) communication technology, Through microelectronic control circuits, it converts the pulse signals of traditional mechanical meter into electrical signals. Then the metering data is transmitted to background platform through NB IoT network automatically

Main Features

  1. Directive 2014/32/EU, OMIL R-49:2013(E)& EN14154 compliant
  2. Wet dial / dry dial register construction on request
  3. Magnetic field protection
  4. Low battery consumption design, Up to 8 years' battery life
  5. Large capacity data storage
  6. Recording meter’s running information
  7. Including 36 months of time-slicing information for the district metering monitoring
  8. Brass / plastic meter body on request
  9. Over 10 years’ data storage in absence of power
  10. Non- return valve preventing back-flow
