Wireless M-BUS transmission module for water meters
The RFM-TX1 is a radio module suitable for the water consumption data radio transmission applicable to the single jet GSD8-RFM water meters.
Easy to install and configure, it is designed with ultra-low power consumption components and special algorithms for energy savings.
In addition to the actual consumption and up to 12 months of historical values, it can detect several fraud attempts against the meters, maximum flow rate (Q4) exceeded and plumbing system downstream leakage.
