Rainwater Management
The First Rain Display & Regulator connects to a rain gauge to monitor and regulate rainfall events in real time. It provides information on rain status, distinguishing between no rain, first rain, and further rain conditions. Configurable parameters allow users to set specific thresholds (T1, T2, Qp) to determine these statuses, with relay outputs signaling rain conditions to control external systems.
​
The system defines "first rain" as the initial 5 mm of rainfall within a given period. Once precipitation exceeds this threshold, it transitions to the "further rain" condition. The DGP020 display unit, when connected to a rain gauge, continuously updates total rainfall, intensity, and duration, ensuring precise monitoring.
​
Rain status is categorized based on specific conditions. The "no rain condition" occurs when there is a dry period lasting at least T1 minutes, and any precipitation during this time initiates the transition to "first rain." The "first rain condition" begins with rainfall following a dry period or short rain intervals under T2 minutes. This phase continues until the cumulative rainfall reaches Qp mm, transitioning to "further rain." If rain stops for longer than T2 minutes, the system resets to "no rain." The "further rain condition" follows the first rain phase and continues as long as no rain-free intervals exceed T1 minutes. A longer dry period shifts the system back to "no rain." The First Rain System consists of a rain gauge connected to a regulator housed in an IP65-rated enclosure. It can be mounted on a pole and linked to electric pumps that control the opening and closing of first rain tanks, ensuring efficient water management.
