 Rain Gage installation instructions

1. Installation location selection: according to the actual demand, the sensor can be installed on the ground, homemade large cylinder, iron post flange or the roof of the house.

2. Leveling and fixing:

   - Adjust the three leveling screws on the chassis so that the leveling bubble indicates level.

   - Slowly tighten the expansion screws for fixing to ensure that the sensor is stable.

   - If the leveling bubble changes, readjustment is required.

3. Sensor assembly: assemble and fix the sensor according to the diagram. 

4. Function test: After fixing, open the rain barrel, cut off the nylon tie on the funnel, fill in water to check the tipping of the bucket and the data reception of the collecting instrument.

5. Caution:

   - Avoid disassembling the sensor during installation to ensure correct installation.

   - Do not connect the wires with electricity, and do not turn on the electricity until the wiring is completed and checked.

   - Sensor wire length will affect the product output signal, do not change the welded components or wires.

   - Regularly check the sensor, remove dust, mud, sand and other debris to ensure that the water flow channel is smooth.

   - When there is dirt on the inner wall of the tipping bucket, it can be rinsed with water or alcohol, and it is strictly prohibited to wipe it with fingers or other objects.

   - During winter icing, the instrument should be out of use and taken back indoors for storage.

 Precautions for using Rain Gage

- Check the package and model number: Please check whether the package is intact, and check whether the product model number is consistent with the selection.

- Safe wiring: Do not wire with electricity, check that the wiring is correct before turning on the power.

- Avoid alteration: the sensor wire length will affect the product output signal, do not change the welded components or wires.

- Regular maintenance: check the sensor regularly, remove dust, mud and sand and other debris to ensure that the water flow channel is smooth.

- Cleaning the tumbler: when there is dirt on the inner wall of the tumbler, it can be rinsed with water or alcohol, and it is strictly prohibited to wipe it with fingers or other objects.

- Winter use: During winter icing, the instrument should be out of use and taken back indoor for storage.

- Save certificates: Please save the calibration certificate and certificate of conformity and return them with the product when repairing.

 Integrating the 8 inch Rain Gage with Other Devices

Integrating the 8 inch Rain Gage into other equipment or systems typically involves the following key steps and technical points:

1. Select the appropriate communication interface:

   - The 8 inch Rain Gage provides a variety of output forms, including switching signals, voltage signals (0~2.5V, 0~5V), and RS485. depending on the reception capabilities of the target system, select the most appropriate communication method. For example, if the target system supports digital communication, RS485 is an ideal choice because it supports long-distance transmission and is resistant to interference.

2. Configure the communication protocol:

   - For RS485 interface, you need to make sure that the sensor and the receiving device use the same communication protocol and baud rate. RS485 usually adopts Modbus RTU protocol, which needs to be configured on the system side with the corresponding read commands to get the data.

3. Power supply compatibility:

   - Verify that the power requirements (DC 5V, 12V-24V) of the 8 inch Rain Gage match the power output of the integrated system to ensure stable power supply.

4. Physical Installation and Wiring:

   - Follow the installation instructions to ensure that the Rain Gage is mounted in the proper location and wired correctly. For outdoor installation, also consider protecting the connection points from the environment.

5. Data processing and calibration:

   - After integration, code or configuration software needs to be written on the system side to properly parse the data received from the rain gauge. For applications requiring high accuracy, field calibration may also be required to ensure the accuracy of the measured data.

6. System integration testing:

   - Once integration is complete, system testing is performed to simulate precipitation and verify that the data are accurately and correctly transferred to and displayed through the system or further processed. This step includes checking the real-time, accuracy, and stability of the data.

7. Software integration and automation:

   - For complex systems such as weather monitoring networks or automated irrigation systems, integration at the software level is critical. Ensure that rainfall data can trigger appropriate automated processes, such as alarms, data analysis or control actions.

8. Long-term monitoring and maintenance:

   - After integration, regularly check the stability of the communication connection and the performance of the rain gauge to ensure long-term operational reliability.

 Conclusion

The 8 inch Rain Gage is more than just a piece of technology, it's a powerful tool for environmental monitoring. With excellent performance, flexible configuration and easy maintenance, it is an indispensable tool in the professional field, contributing to the protection of the natural environment and the safety of human life.
