Variable-area flow meter N_Type

volumefor liquidsfor gas

Operation Principle The variable area flow meter content a float & taper tube. The fluid flow through the taper tube and force up to the float. The flow rate is measured as a function of the area of the opening. This area displayed as the float that is free to move to produce the varying area. Technical Data A.
