nnnnOperation
nnnnThe fluid flows through the meter and displaces the
nnnntarget disc with a force proportional to the flow. The disc
nnnnmovement is restricted with a coil spring until a force
nnnnbalance is achieved between the force from the fluid and
nnnnthe torsion of the spring. The equilibrium position of the
nnnntarget disc is proportional to the flow rate and provides
nnnnthe measurement of flow.
nnnnThe position of the disc is transferred to the flow
nnnnindicator by means of magnetic coupling.
nnnnThis magnetic coupling avoids fluid leakage to the
nnnnindicator box.
