The CM Series mass flow meters utilize industry's well recognized high accuracy standard, Coriolis technology. The core operating principle of this technology is that fluids flow through a vibrating tube which then causes a deflection of the flow tube proportional to mass flow rate. It is suitable for use with liquids, gases and slurries. Models are available that will measure mass flow, volumetric flow, temperature and density. Unaffected by variations in pressure, temperature, density, electrical conductivity and viscosity, the CM Series provides extremely accurate mass flow measurement over wide flow ranges. The series is comprised of three (3) models which differ by their choices in flow range, wetted parts, accuracy, pressure ratings, density measuring, and other optional functions and features.
