Product Introduction
The RD-300-CR is a non-contact, planar integrated radar water level station designed for surface water level measurement. It utilizes Frequency Modulated Continuous Wave (FMCW) radar technology to measure liquid levels. This energy-efficient, non-contact measurement technology ensures that the readings are unaffected by temperature gradients, surface vapor, water contaminants, or sediment. The optimized algorithm enhances the accuracy of the measurement results. Equipped with a built-in RTU, Bluetooth, rechargeable lithium battery, and solar charging control board, the station only requires an external solar panel to form a fully operational water level monitoring system. Compared to traditional discrete water level gauges, it offers advantages such as lower overall costs, ease of installation, and minimal maintenance requirements.
