A device installed in a piping system to measure the continuous rate or total volume of a passing liquid or gas. They operate on various principles, such as differential pressure, electromagnetic induction, or ultrasonic transit time, depending on the fluid properties and required accuracy. Engineers rely on them to monitor process efficiency, bill for utilities, and control mixing ratios in automated systems.

Check the ultrasonic flow meter on the chilled water loop; it's reading zero but the pump is definitely running.
