The water flow velocimeter adopts non-contact high-frequency radar flow measurement technology, which can be applied to hydrologic measurement, water resource monitoring, urban road flood control, mountain flood early warning, environmental pollution monitoring, etc.
Compared with the existing contact current meter and various Doppler acoustic and ultrasonic flow measurement technologies and equipment, the non-contact radar flow measurement method is easy to maintain at any time, is basically free from water damage, sewage corrosion, and sediment, and ensures the safety of personnel. It can not only be used for environmental monitoring at ordinary times, but also especially suitable for undertaking urgent, difficult and dangerous observation tasks.
