The DAB NFC Water Level Sensor is specifically designed for compatibility with the DTRON3 and ESYBOX Diver models, facilitating a direct connection to the DConnect BOX2 for real-time monitoring of water levels. This sensor alerts users about tank water levels via the DConnect app, enabling effective system management. Additionally, both the NFC Water Level Sensor and NFC Float can be integrated without affecting the watertight integrity of the pump due to the inclusion of the NFC (Near Field Communication) pocket.
