How It Works

The HydroSpider was designed to easily fit into most standard TBRG

Tipping Bucket Rain Gauge (TBRG) in a weatherproof enclosure, with a HydroSpider 2 inside.
  • Deploy HydroSpider2 in the field, attaching your sensors and securing the unit in place.

  • Configure locally using the LANLink or HLink cable and a computer via web browser. No special software required. 

  • HydroSpider2 automatically collects and transmits data. Alarms can be set to notify you of critical changes, and reports are delivered on schedule.

  • HydroSpider2 provides you with actionable data for decision-making, ensuring compliance and enhancing water management strategies.

Applications
