    ADW is a special compact design, reliable, absolute achievement in high accuracy measurement & water-proof protected meter. The accuracy is guaranteed even if it is installed underwater in a long time.

Technical Specification

Flow Sensor

    The flow sensor is a device used to measure the velocity of flow by using the principle of ultrasound. It can measure the average velocity along the path of an emitted beam of ultrasound by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow. The flow measurement is based on an acoustic wave time of flight principle. The flow meter body is equipped with 2 ultrasonic transducers facing 2 acoustic reflectors.
