MeiStreamRF infrastructure
The MeiStreamRF has SensusRF integrated technology providing the advantages of both uni and bidirectional system architecture as described below. SensusRF is the optimized license free radio system for battery driven endpoints and repeaters. Scalable for mobile and remote reading without exchange of components, it is available in 433 MHz.
SensusRF offers two communication modes
1. Fixed Radio Network
Auto configuration wizard (gateway sniffing for endpoints and repeaters)
Integrating repeaters (up to 7 hops in a chain)
Self-healing network (using alternative routes)
Meter reading transparent and local
Fast track alarms
DMA snap shot (snap shot of a water network for evaluation)
TCP/IP technology for the WAN communication
High level of data security (end-to-end encryption)
Enables cloud technologies, FTP and other remote database applications
2. Mobile read - Walk-by / Drive-by
Unidirectional telegrams
Bidirectional communication
Spontaneous reception possible without route
Configuration of the endpoint SIRT (Sensus Interface Radio Tool)
SIRT is a radio modem for SensusRF radio, connected to a handheld via Bluetooth and using Sensus Diavaso Mobile Reading software with the following features:
Installation and readout of devices
Reception of frequently transmitted radio messages from Sensus RF radio endpoints
Request additional information from the radio endpoints
Change configuration of radio endpoints (alarm, level settings... )
