The role of a flow meter is to perform a measurement that answers questions like, how many liters of flow do we have currently or how many liters have we used so far? Flow meters are actually used in a wide variety of areas. For example, flow meters play a vital role in situations such as stopping the supply of fuel once you have 10 liters of gasoline, or administering only 500cc of medicine to a hospital patient. The primary role of flow meters in the Factory Automation field is to manage the flow of "water".
The use of this "water" varies according to the application and it is sometimes referred to as "coolant", "cooling water", "cutting water", or "grinding water". In addition, recent energy conservation laws and traceability requirements have expanded the general need for flow meters.
