3. Introduction Volumetric flow rate:
The volumetric flw rate of a system is a measure of the volume of fluid passing a point in the system per unit time; it՚s usually represented by the symbol Q (sometimes V̇).

15. Ultrasonic flowmeter

16. Ultrasonic flowmeter
Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe.
There are two kinds of ultrasonic flowmeter:
Doppler
Transit time

17. Doppler flowmeter

18. Doppler flowmeter Advantages: Disadvantages: Usages:
Obstruct less flow
Can be installed outside the pipes
The pressure drop is equal to the equivalent length of a straight pipe
Corrosion resistant
Relative low power consumption
Disadvantages:
the usage of this is limited to the fluids that have bubbles or particles; for example we cant use this for measuring the gas; we have to be care about sludges.
Usages:
for the fluids that have high temperature,water,oil,acid.

19. Transit time flowmeter

20. Transit time flowmeter
Reflex mode
Reflex mode (double
Bounce)
Reflex mode (triple
bounce)

21. Transit time flowmeter
Diagonal mode
Disadvantages:
For the fluids that have high speed is not suitabl; we have to be care about sludges.

27. Questions Explain Doppler and Transit time flowmeters
How we can put the sensors on pipe in transit time model and what parameters it՚s depends on?
Why we can՚t utilize Doppler flowmeter in gas industry?
