5. Operation
The TFA Dostmann Analog Rain Gauge operates automatically. As rain falls, it collects in the measuring cylinder, and the red float rises with the water level. The scale on the side of the cylinder indicates the amount of precipitation in millimeters (mm) or liters per square meter (L/m²).
Reading the Rain Gauge:
- Observe the position of the red float against the black scale.
- The top edge of the red float indicates the current precipitation level.
- Read the value directly from the scale.
- For accurate daily or weekly measurements, empty the gauge after each reading or at regular intervals.
6. Maintenance
Regular maintenance ensures the longevity and accuracy of your rain gauge.
- Emptying: The measuring cylinder is removable for convenient emptying. Simply lift the cylinder from its bracket, pour out the water, and replace it.
- Cleaning: Periodically clean the measuring cylinder and float with mild soap and water to remove dirt, debris, or algae that could affect accuracy. Rinse thoroughly with clean water.
- Winter Storage: During winter months, especially in areas prone to freezing temperatures, it is crucial to empty the rain gauge completely or bring it indoors to prevent damage from ice expansion.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Rain gauge is not level; obstructions are blocking rainfall; debris inside. | Ensure the rain gauge is installed on a level surface. Relocate if obstructions are present. Clean the cylinder and float. |
| Red float is stuck or missing | Debris obstructing float movement; float was not included in package. | Clean the inside of the cylinder. If the float is missing, check package contents or contact customer support. |
| Cracked cylinder | Water froze inside the cylinder. | Replace the damaged cylinder. Always empty the rain gauge before freezing temperatures. |
