Product Introduction
The RD-306 is a high-precision, low-power, and highly integrated non-contact integrated radar water level meter / open channel flow meter.

This product integrates functional units such as a power supply battery, high-precision radar level gauge, RTU data transmission unit, Bluetooth parameter adjustment, and temperature measurement, making it suitable for liquid level and flow measurement across various industries. Its flow measurement principle is based on the water level-flow relationship of standard weirs or rating curves. By accurately measuring the liquid level, it calculates and outputs the instantaneous flow and cumulative flow at the cross-section. The liquid level measurement employs high-precision Pulse Coherent Radar (PCR) technology, which offers higher measurement accuracy, lower power consumption, and a more compact size compared to traditional pulse radar level gauges. Additionally, the use of 60G/80G sub-millimeter radar waves as the carrier signal provides non-contact, high-precision, compact, and energy-efficient characteristics. This ensures that measurements are unaffected by corrosion, temperature gradients, air pressure, surface vapor, bubbles in water, or sediment. The optimized algorithm further enhances the accuracy of the measurement results.

It can be widely applied in projects such as irrigation district informatization, underground pipe networks, urban flood monitoring, and well monitoring. It offers high cost-effectiveness in various applications, including flow measurement in open irrigation channels, main and branch canals, and pipe networks.
Product Features
