Product Options


The ISCO 2103c CDMA Cellular Modem allows you to download data remotely from 2100 series flow modules, and is factory configured to work with a variety of mobile phone service providers. This modem can eliminate costly land line installations, the need for repeated site visits and the need for costly and potentially dangerous confined space entries.

Using economical 1xRTT packet-switched data transmission, the modem can transmit flow data remotely via the internet at user specified intervals, to a server running ISCO Flowlink Pro software (an Oracle or Microsoft SQL database is required to utilise this feature. contact RS Hydro for more information). The user specified transmission interval (from 5 minutes to 24 hours) can be set to change to a secondary interval when certain site conditions are met.

Standard Features of the 2103C Include:

  • High data transmission (up to 28.8 kbps)
  • Automatic alarm messaging to mobile phones or pagers
  • Resistance to lightning damage
  • Long battery life. The unit will power on when user set dial-out conditions are met, but the user can set specific times for dial-in communications which significantly increases battery life.
  • Compatible with Isco Flowlink data management software, enabling sophisticated graphing, reporting, editing, analysis and archiving
