Variable area flow meter measures the fluid flow based on the throttling principle, but it changes the flow area of the fluid to keep the differential pressure between the top and bottom of the rotor constant, so it is also called a variable flow area constant differential pressure flowmeter, also called a float flow meter ,variable area flow meter .
