The RD-300 series radar level gauge is a non-contact planar radar level gauge used for measuring surface water levels. It employs Frequency Modulated Continuous Wave (FMCW) radar technology to measure the liquid level. This energy-saving, non-contact measurement technology makes it unaffected by ambient temperature, water vapor pressure, air dust, pollutants, and sediment in the water. Optimized algorithms ensure more accurate and stable measurement results. A mobile app connects wirelessly via Bluetooth for convenient on-site debugging and maintenance. This series of level gauges can also be equipped with a built-in RTU function, which directly uploads on-site data to a cloud platform via a built-in wireless communication unit, enabling remote debugging and equipment program upgrades. It features high integration, small size, easy installation, and low maintenance.
