KNF-131 radar level gauge, tide gauge, water level gaugeIt is a high-precision, low-power radar level gauge that can be used for non-contact level measurement in surface water, seawater tides, drainage pipe wells, and other occasions; The device adopts pulse coherent radar (PCR) technology, using 60G millimeter wave radar as the carrier signal, and achieves millimeter level measurement accuracy through complex signal recognition algorithms. The optimized wave attenuation filter design makes the measurement results more accurate and stable. Compared to traditional pulse radar level gauges, it has higher measurement accuracy, lower power consumption, and ultra small size; It is a cost-effective radar level gauge that is not affected by temperature gradients, air pressure, water vapor, water pollutants, and sediment during measurement.
