SPDV200F Doppler Open Channel Flowmeter

SPDV200F Doppler Open Channel Flowmeter can obtain the velocity of the fluid by measuring the Doppler frequency shift of the sound waves scattered by the moving particles in the fluid. Combined with the built-in pressure water level gauge, the velocity area method can be used to measure the flow of the liquid. The display can designed with handheld meter or wall-mounted display meter.

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.
