NexSens G2-RAIN User Guide

The NexSens G2-RAIN Alert System is a self-contained rain monitor with an integrated precision rain gauge and real-time data alerts. It transmits accurate rainfall measurements directly to WQData LIVE’s cloud based data management platform using internal power and an embedded cellular modem.

Installing and Removing the Siphoning Bucket

The siphoning tipping bucket forces rainfall to flow directly onto the tipping apparatus, which allows for accurate precipitation measurements.

Follow the subsequent steps to remove the tipping bucket:

  1. Remove the siphoning tipping bucket from the G2-RAIN-RTU by using the 9/64” hex wrench to loosen the (3) bolts that are connecting the bucket and the RTU.
    1. Reference the G2-RAIN diagram below

  2. Slide the bucket clockwise until the (3) bolts on the side of the G2-RAIN-RTU are aligned with the vertical portion of the L-shaped slots on the side of the bucket.

  3. Lift the bucket up gently.
    1. Note: During the bucket’s first removal, ensure to remove the rubber band from the tipping apparatus.

  4. Reinstall the bucket by aligning the vertical portion of the L-shaped slots with the (3) bolts on the side of the RTU. Rotate counter-clockwise and re-tighten the bolts.

Power and Connection Sources

The Nexsens G2-RAIN Alert System comes with either a pre-installed internal Lithium battery pack or an AC power adapter. The system also includes an SMA antenna and an SMA right angle adapter for telemetry connection.

Telemetry Connection

Attach the SMA antenna to the copper threads found on the bottom of the G2-RTU.

  • If necessary, use the SMA right angle adapter to adjust the direction of the antenna for connection purposes.

Power

Use the internal Lithium battery pack as a power source by utilizing the Nexsens flathead screwdriver to twist the power plug found on the bottom of the G2-RTU to the “ON” position.

  • Twist the power plug until a single audible beep is heard. This confirms the power connection.

Internal power connection

 

Use external power by either connecting the G2-RTU adapter cable to an SP-Series solar panel or an AC power adapter.

  • Listen for the beep to confirm power connection.

Mounting the G2-RAIN System

Thread the base of the G2-RAIN system onto a pre-installed galvanized steel or aluminum 2″ NPT pipe at the deployment location.

  • Carefully rotate the G2-RAIN system clockwise until the system is securely attached to the pipe.
    • The gauge should sit level to ensure that the acquired data provides the best representation of the rainfall.
      • A leveling fixture is located adjacent to the tipping mechanism beneath the siphoning bucket for reference.
