KNF-131Radar level gauge is a high precision, low power consumption instrument that can be used for non-contact level measurement in surface water, tidal, and drainage pipe Wells. The equipment uses pulse coherent radar (PCR) technology, 60G mm radar wave as the carrier signal, through the complex signal recognition algorithm to achieve the millimeter-level measurement accuracy, optimized wave filtering design, make the measurement results more accurate and stable. Compared with the traditional pulse radar level gauge, it has higher measuring accuracy, lower power consumption and ultra-small volume. Measurement is not affected by temperature gradient, pressure, water vapor, water pollutants and sediment, is an ultra-cost-effective radar level gauge.
