Product Data Sheet

RFM-LR1 has been designed to allow wireless remote reading in different types of applications in the residential sector.

The radio module thanks to the presence of the optical target into the meter dial allows the reading of the volume consumption without any constraints of access to the site thanks to the Long Range LoRa radio technology and the compliance to the LoRaWAN standard can be intergated into multi-service networks.

  • Radio interface: LoRaWAN @868 MHz ≤ 25 mW
  • Network joining methods: OTAA, on request ABP
  • Frequency of transmission: 4 per day
  • Coverage: Up to 5 Km*
  • Compatible water meters GSD8-RFM
  • Pulse output minimum value (K): 1 litre
  • Configuration: Via downlink commands from LoRa network
  • Energy supply: Non-replaceable lithium battery, maximum lifetime 10 years**
  • Protection class: IP68***
  • Weight: 84 g
  • Size (l x d x h): 26 x 26 x 13 mm
  • Working Temperature: +1° - +55°C
  • Transmitted data: Volume (consumption), total of backward flow, alarms
  • Alarms: Discharged battery, module removal, magnetic fraud attempt, backward flow, leakage detection

* In optimal signal transmission conditions
** The battery life strongly depends on the working time window, set during the configuration process, and on the environmental conditions
*** IP68: maximum 24 hours of continuous submersion at 1 m depth.
