A flow meter is used to measure and quantify fluid movement. There are different types of flow meters, including mechanical flow meters, pressure-based meters, optical flow meters, thermal mass flow meters, and vortex flow meters, to name a few.
Mechanical flow meters also come in many forms. Some types include bucket-and-stopwatch meters, piston meters, variable area meters, the Woltmann meter, the turbine flow meter, and the single jet meter. The easiest way to measure volumetric flow is to measure how long it takes to fill a container of known volume. This is done with a bucket-and-stopwatch meter. If you are just starting to understand the process of using a flow meter, this may be the system you will want to use.
Optical flow meters use light to tell you the rate of the flow. Basically, this flow meter uses one laser to create a pulse signal that is delivered to another down the line of the tube. This type of flow meter requires less maintenance and is less prone to errors over its lifetime.
