Product Introduction
The RD-300 series radar water level meter is a non-contact planar radar water level meter designed for surface water level measurement. It utilizes Frequency Modulated Continuous Wave (FMCW) radar technology to measure the liquid level.
This energy-efficient, non-contact measurement technology ensures that the measurements are unaffected by environmental temperature, water surface vapor pressure, airborne dust, water pollutants, and sediment. The optimized algorithm enhances the accuracy and stability of the measurement results. A mobile APP connects via Bluetooth for convenient on-site debugging and maintenance. This series of water level meters can also be equipped with a built-in RTU function, allowing the on-site data to be directly uploaded to a cloud platform through the built-in wireless communication unit, and enabling remote debugging and device program upgrades. It features high integration, compact size, easy installation, and minimal maintenance requirements.
