Type of flowmeters

Question

Type of flowmeters

Accepted Answer

Flowmeters are devices used to measure the flow rate or quantity of a gas or liquid moving through a pipe.

There are several types of flowmeters including differential pressure, positive displacement, turbine, electromagnetic, ultrasonic, and vortex flowmeters.
Differential pressure flowmeters measure the pressure drop across a constriction in the pipe.
Positive displacement flowmeters measure the volume of fluid passing through the flowmeter.
Turbine flowmeters measure the velocity of the fluid passing through the flowmeter.
Electromagnetic flowmeters measure the voltage generated when a conductive fluid passes through a magnetic field.
Ultrasonic flowmeters use sound waves to measure the velocity of the fluid.
Vortex flowmeters measure the frequency of vortices shed by a bluff body placed in the flow stream.
