Flow Meters

Devices vital for various industrial and commercial applications, flow meters serve to measure the flow of different kinds of media. For exceptionally accurate flow measurements across a wide variety of gases, liquids, and airs, many industries tend to prefer a differential-pressure flow meter. Though these devices can be quite complex, the basic construction of a differential-pressure flow meter is relatively simple. Pressurized fluid flows through a pipe that is constricted in some way (in this case, an orifice plate), creating a pressure differential between the upstream and downstream sides of the constriction. With a basic equation from fluid dynamics, this pressure differential can then be used to calculate the flow rate through the pipe.

Flow meters that measure mass are particularly well-suited for applications demanding accurate control of gas and liquid flows. Such applications are common in many industries, including chemical processing and process control operations. Mass flow meters are reliable—they provide continuous flow measurement without the need for moving parts, which means there's less to go wrong.
