Function

The OPTIMASS 7300C measures flow using the Coriolis principle. As fluid passes through vibrating measuring tubes, the Coriolis effect causes a phase shift proportional to the mass flow rate. The instrument simultaneously calculates density from the tube vibration characteristics and measures process temperature using integrated sensors. This allows multiple process variables to be measured accurately using a single device.
