Operation of Disc Target Flowmeter - Series DP-65 & DP-500:

The fluid flows through the meter and displaces the target disc with a force proportional to the flow. The disc movement is restricted with a coil spring until a force balance is achieved between the force from the fluid and the torsion of the spring.

The equilibrium position of the target disc is proportional to the flow rate and provides the measurement of flow.The position of the disc is transferred to the flow indicator by means of magnetic coupling.This magnetic coupling avoids fluid leakage to the indicator box.
