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).

Introduction Here is two question?! 1.Why is it important? 2.where is it used? In gas pipes

Introduction In chemical In oil

Ultrasonic flowmeter

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

Doppler flowmeter  

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.

Transit time flowmeter  

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

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

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?
