Frequently Asked Questions
What is radar water level sensor?
A non-contact sensor that measures water levels continuously using high-frequency radar without physical contact with the water.
How does non-contact monitoring work?
It uses radar and Doppler technology to determine water level and surface flow velocity remotely from above the surface, functioning safely during heavy floods and turbulent flows.
Can system work in remote areas?
Yes. The system utilizes solar power with a 15-day backup and supports multi-network connectivity including optional Satellite, specifically designed for unattended operation.
How is data transmitted?
Data is transmitted securely through a fail-safe multi-network mode supporting 4G LTE/GSM, LoRa/NB-IoT, or local Wi-Fi, buffering data locally if the network goes down.
