Flat radar water level gauge

Description :

　　HR 7311 radar water level gauge

　　Introduction:

　　HR7311 radar level gauge is a high-precision, low-power non-contact radar level gauge designed by our company. It can be used for surface (or pipe network) water level measurement; Due to its pulse coherent radar (PCR) technology, which has higher measurement accuracy, lower power consumption, and ultra small size compared to traditional pulse radar level gauges. At the same time, it uses 60G submillimeter radar waves as carrier signals, with high accuracy and small size. The volume and energy-saving characteristics make it unaffected by temperature gradients, water vapor, water pollutants, and sediments. The optimized algorithm makes the measurement results more accurate.

　　Small in size, weighing less than 300 grams

　　High precision, up to millimeter level

　　Easy installation and debugging, maintenance free

　　Algorithm optimization to eliminate the influence of water waves
