Applications

The 640C/640MC is a high precision meter.

Due to its unique piston and measuring chamber design, the smallest dropsof water are measured.With the 640C/640MC you are assured of lasting metrology. The 640C meter range includes an electronic register with integrated radio functionality which enables easy and fast communication.

Due to our broad range of system solutions you can adapt the 640C/640MC to all your AMR, AMI requirements. The protection class of the electronic register of the 640C family is IP 68.With a tamper proof design and its long life span you can be confident when selecting the 640C/640MC

Accuracy and Reliability

Thanks to the advanced design of its measuring chamber the meter has a low starting flow. It can be supplied with metrological seal according the MID regulation 2004/22/EC with a ratio up to R400.

Foreign matter present in the water is filtered out by either the tubular strainer on the inlet or the seat strainer. All electronic components of the register are hermetically sealed and assembled in a glass copper casing which allow the protection class IP68. The 640C/640MC water meter retains its metrological accuracy for many years of operation,even in difficult working conditions.

Infrastructure

The 640C product range 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 forendpoints 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 or evaluation)
  • TCP/IP technology for the WAN communication
  • High level of data security (end-to-endencryption)
  • Enables cloud technologies, FTP and otherremote 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 SensusREAD 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... )
