Flowmeter is a measuring instrument, it can indicate and record the flow value of the instantaneous fluid, accumulate the total value of the fluid in a period of time interval, and measure the volume flow and mass flow. Flow meter according to the more commonly used measurement methods, generally can be divided into volume type, speed type, differential pressure type, mass flowmeter and other types
