How a Flow Meter Works | Types of Flow Meters | RealPars

The principle behind these meters is that an ultrasonic signal is transmitted downstream or in the direction of the flow while another signal is transmitted upstream. The delta or differential time is used to calculate the velocity of the liquid. That velocity is then used to calculate the volumetric flow through the pipe.

Principle of mass flow meter - SlideShare

In a Coriolis mass flow meter, the "swinging" is generated by vibrating the tube (s) in which the fluid flows. The amount of twist is proportional to the mass flow rate of fluid passing through the tube (s). Sensors and a Coriolis mass flow meter transmitter are used to measure the twist and generate a linear flow signal.
