RFM-LR1 Lorawan Radio module for pre-equipped single jet water meters

 

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 integrated into multi-service networks.

• Consumption analysis with reverse flow compensation that provides an always perfect alignment between the counter and the
  counter clock.
• Fraud control (removal of the radio module, application of external magnetic field, reverse flow, identification of system loss).
• Magnetic tampering at the counter and removal are recorded and reported to the receiving system via radio transmission.
• The presence of reverse flow is recorded in an additional register that allows to calculate the amount of water passed in reverse.
• The loss function can be monitored at the time of reading or by the AMR system if a timely update is desired.
• IP68 protection* allows the use of the module also for meters installed in difficult environments.
