OTT HydroMet

- 2-Way Logging Transmitter



The GPRSLink provides simple telemetry anywhere. GPRSLink has two purposes: (1) to collect and store data from meteorological and hydrological sensors, and (2) to send that data wirelessly to a central system, phone or other station. GPRSLink includes a quad band GSM cell phone modem that can operate when the unit is within range of a cell phone network of companies like AT&T and T‐Mobile. Sutron’s Multi-Sensor Input Logger plus flexible, economical 2-Way GPRSLink now has WiFi capability for complete station set-up & data access.

Telemetry via GPRS

  • Periodic transmissions at user set times with data in user selectable format (pseudobinary B, C, SHEF & ASCII)
  • Support for primary and secondary master stations via GPRS
  • Alarm transmissions as they are detected.
  • Diagnostics to help track of the amount of data being sent and the performance of the telemetry
  • Support for remote commands for data collection, maintenance or control of two on/off devices
  • Optional authentication of incoming messages to insure they are from a trusted source & optional authentication of messages sent to SUTRONWIN via GPRS
  • SMS transmissions if GPRS fails or in place of GPRS
  • Extremely affordable
  • GPRS modems use wireless cellular technology and provide data access in most areas where a typical cell phone works.
