The application principle of SPDV200 ultrasonic Doppler current meter is that the ultrasonic sensor is placed in the measured channel and river channel, and the sensor sends ultrasonic wave to the water. According to the reflected ultrasonic signal strength and other parameters, the water velocity can be calculated, and these data are transmitted to the user through the built-in hardware and software. It is widely used to measure the velocity of water in pipelines, channels or rivers.
