Product Options


The ISCO 2103G GSM/GPRS Telemetry Modem module allows the user to retrieve data and communicate remotely with a stack of 2100 series flow meters. This can eliminate the need for land-line installation, repeated site visits, and costly and often hazardous confined space entries.

The 2103G is compatible with user-subscribed GSM mobile phone services (T-mobile, O2 etc) via a standard SIM card which is placed in a waterproof port on the base of the module. Service parameters or provider can be changed by simply replacing the SIM card.

Data can be sent automatically via the internet using economical GPRS packet-switched data transmission. The data retrieval interval of between 5 minutes and 24 hours can be set by the user and the 2103G can be configured to automatically switch to a secondary interval when user set conditions are met. Isco Flowlink Pro software and an Oracle or Microsoft SQL database are needed for this functionality (contact RS Hydro for more information).

Standard Features of the 2103G telemetry modem include:

  • Communication possible wherever a GSM mobile signal can be detected
  • Automatic dial out alarm messaging to mobile phones or pagers
  • Resistant to lightning damage
  • Easy setup and service provider can be changed by installing another SIM card
  • Enclosure is NEMA 4X, 6P and IP68 rated
  • Compatible with Isco's Flowlink data management software which enables sophisticated graphing, editing, reporting, analysis and archiving
  • Extended battery life - The telemetry modem can be programmed to power up for data transmission only and power down when complete.
