Sensus - MeiStreamRF Plus - Radio Water Meter

MeiStreamRF Plus is an industrial meter with an electronic register for:

• Measurement for billing of cold potable water up to 50 °C
• Measurement of medium and high flow rates
• Measurement of low flow (e.g., in light load period)
• Leakage control
• Integration into smart water systems

The MeiStreamRF Plus has SensusRF integrated radio technology, providing the advantages of both unidirectional and bi-directional communication. SensusRF is an optimized radio system for battery-driven endpoints. Scalable for mobile and remote reading without the exchange of components, it is available in 433 MHz.

MeiStreamRF Plus infrastructure

The MeiStreamRF Plus 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 the exchange of components, it is available at 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)
• The meter reading is transparent and local.
• Fast track alarms
• DMA snapshot (snapshot 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 is 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 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... )
