What are the factors that affect the measurement of ultrasonic flowmeters?
1. fluid medium(ultrasonic flowmeter can also be measured in the media, some media can not be measured)Temperature of 2. medium3. whether the full tube (liquid ultrasonic flowmeter)?4. time difference method of ultrasonic flowmeter can only measure more pure liquid flow.5. Doppler ultrasonic flowmeter specially designed to measure liquid flow with impurity bubbles6. pipe material7. wall thickness of pipe8. the velocity range of the medium (too low or too high) is not accurate
The distance of the sensor probe (referring to the time difference method of ultrasonic flowmeter, which is measured by the refraction of the ultrasonic wave, is also very large if the distance is not correct)
When the sensor probe contact the pipe wall is sufficient contact, the general pipe wall needs to be polished treatment, coupled with a mixture to achieve full contact, if the poor contact will affect the signal transmission
