Product Options



The 2103 Wireless Modem Module provides reliable two-way communication between downhole 2150 series flow modules and a computer running Isco Flowlink software. The 2103 automates remote data retrieval in sewer flow studies, eliminating the need for confined space entry and frequent site visits.

The user can specify intervals at which data is transferred to a computer running Isco Flowlink software (an Oracle or Microsoft SQL database is needed to utilise this feature). The module can also be set to send a text message alarm to a mobile phone or pager.

The 2103 modem stacks with other Isco 2100 series modules, creating an integrated system for the acquisition, storage and communication of open channel flow data.

Standard Features of the 2103 include

  • Interrogation of instruments via Isco Flowlink software
  • Reliable data retrieval for the convenience of your office
  • Remotely set any parameters (e.g. data interval)
  • Set a data retrieval schedule using Flowlink software to dial and download all data from your site network while you are away. Data will be graphed and ready when you return to your desk
  • Automatic dial-out alarm for level
  • Moisture-tight connections and rugged, NEMA 4X, 6P (IP68) case
  • Enhanced error correction protocols for noisy lines
  • up to 33.6 kbps communication - 10 times faster that a typical 2.4 kbps modem
