SINOSO RDFM radar Doppler open channel flowmeter adopts advanced millimeter wave radar technology to measure the velocity and water level of the water body through non-contact mode. According to the built-in software algorithm, it calculates and output the real-time section flow and cumulative flow. It can be used for flow measurement in river, irrigation channel and other scenarios. It is not affected by temperature gradient, pressure, air density, wind or other meteorological environmental conditions, and is not affected by sewage corrosion and sediment. It can work stably all weather, and is suitable for general river and channel flow measurement, especially for high-standard farmland, water ecology, water conservancy, velocity flow measurement.
