[0002] A flow meter is an instrument used to measure the flow of fluid in a pipe or open channel. It can indicate the measured flow rate and the total amount of fluid in a selected time interval. There are many types of flow meters. According to different measurement principles and technical characteristics, they can be divided into differential pressure flow meters, turbine flow meters, electromagnetic flow meters and other types.
