flow velocity measurement

Flow velocity measurement involves determining the speed at which a fluid (liquid or gas) moves through a pipe or channel. Techniques include using devices like flow meters, which can employ electromagnetic, ultrasonic, or mechanical principles. For example, ultrasonic flow meters send sound waves through the fluid and measure the time it takes for the signals to travel, calculating the velocity based on these measurements. Accurate flow velocity information helps manage systems more efficiently, ensuring proper operation in industries like water supply, HVAC, and process manufacturing.
