FLOW MEASUREMENT - Coggle Diagram

- - - - 1.A gear drive external to the measuring chamber synchronizes the impellers
        2.During each rotation four crescent shaped volumes are moved through the measuring chamber
        3.The number of rotations is proportional to the flow
        4.The rotation is coupled using an adjustable fine tooth gear train to the totalizer
- - - - formula:
        1.P stat/p + V²/2=P stag/P
        
        V= √2 (P stag/p -P stat/p) p
        
        V= flow velocity
        p=density of the fluid
        P stag= stagnation/total pressure of the free steam given by the stagnation tube.
        P stat= free stream static pressure
