- Between flanges (wafer) for DN-80 to DN-300
- Standard Flanges for DN-250 to DN-500
The fluid flows through the meter and displaces the target disc with a force proportional to 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 through a magnetic coupling. This indirect coupling protects the measurement from any impacts on the disc.
