The H1688-UR Radar-Ultrasonic Integrated Flow Meter is a multi-functional flow meter integrating radar velocity measurement, radar level measurement, ultrasonic velocity measurement, pressure level measurement and water temperature sensor.It embeds models for different application scenarios, and the corresponding scenario algorithms can be selected according to different installation environments.Combining radar and ultrasonic technologies, it adopts non-contact radar measurement for non-full pipe conditions and automatically switches to contact ultrasonic measurement for full pipe conditions.It is mainly suitable for closed, humid, corrosive and submergible on-site environments such as drainage pipe networks and irrigation canal systems, and can easily handle flow monitoring in non-full pipe, full pipe, and switching scenarios between the two states.
