The ultrasonic flowmeter is an advanced device that lets us measure flow rate without any contact with a fluid. It means this flowmeter type is installed on a pipe; so, it is suitable for corrosive fluids or big-size pipelines. This positive point makes it the most applicable device in seawater pipelines or dam control.

You can find several applications for the device in salty and fresh water, sewage industries, crude oil, diesel alcohol, and acids.

One of the advantages of the ultrasonic flowmeter is measuring the volumetric flow rate of liquids; fluid conductivity, temperature, viscosity, and pressure are not effective in the flowmeter work, but one of the disadvantages of the flowmeter is accuracy. Some insertion or in-line models can improve accuracy and might be used in custody transfer applications. 

One of the most advanced applications of ultrasonic flowmeters is flare lines in oil industries.
