Product Data Sheet
Installation Manual
The RFM-TX1 is a radio module suitable for the consumption data transmission and 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 present consumption data and up to 12 months of historical values, it can detect various types of attempted fraud against the meters, the prolonged functioning at the maximum flow rate (Q4) and a potential water loss downstream the meter
