GF ultrasonic flowmeter differential method

When ultrasonic signals are transmitted through a liquid, if they flow in the same direction as the liquid, their velocity will be slightly higher

Micro acceleration, if opposite to liquid flow, the speed will slightly decrease.

The time difference method compares the time required for sound to be transmitted from A to B and from B to A.

Periodic voltage pulses act on the transducer crystal and generate ultrasonic beams of specific frequencies. Ultrasonic beam first

Transferred from downstream transducer (blue) to upstream transducer (red).

Then send the ultrasound beam in the opposite direction, from the upstream sensor (red) to the downstream sensor (blue)

Color). The time required for ultrasound to pass through the liquid in that direction will vary slightly depending on the velocity of the liquid flowing through the pipeline

shortenThe resulting time difference (T1-T2) is proportional to the velocity of the liquid flowing through the pipeline.

Doppler method

11The ultrasonic Doppler sensor continuously emits high-frequency ultrasonic pulses into the flowing liquid through the pipe wall.

Ultrasonic pulses are reflected back by moving particles or bubbles in the medium.

At zero flow, the reflection frequency is the same as the emission frequency.

If there is flow in the liquid, the reflection frequency will be different from the emission frequency (through the Doppler effect, refer to

The change in the sound effect produced by the alarm of an approaching ambulance.

The frequency shift is continuously measured by a Doppler sensor and used to measure the velocity of the medium.
