Mass flow meter

It is called a U-shaped measuring tube. There is a vibration driver inside to drive the tube to vibrate. The electromagnetic sensor installed on the U-shaped bend measures the phase difference of the tube vibration to measure the mass flow rate of the medium flowing through it.
This flow meter is called a Coriolis flow meter (mass flow meter). Its working principle is to pass a thin-walled measuring tube fixed at both ends, and measure the tube at its midpoint, which resonates or is close to resonance. The liquid flowing in the tube produces coriolis, which causes the two halves before and after the midpoint of the measuring tube to deform in opposite directions. The amount of deflection is detected using optical or electromagnetic methods to obtain the mass flow rate.
If you can’t see the pictures on the first floor, the answers to 2/3 are correct. Let me give you a link, FLASH made by MICROMOTION. Based on this, you can clearly understand the working principle of Coriolis force. http://www.emersonprocess.com/Micromotion/tutor/old_tutor/chinese/index.html
It would be great if the above link was in Chinese or had an explanation of the Chinese character knot.
Isn’t what you see in Chinese?
It is a measuring tube. It should be a protective tube on the outside. There is a measuring tube on the inside. The fluid flows through the U-shaped tube.
One of the mass flow meter measuring tubes, it is U-shaped, there are also V-shaped, Z-shaped, etc.
U-shaped tube flowmeter, haha, just go to the chemical engineering principle and you will know, it is very typical
