Industrial Coriolis mass flow meter installed with digital flow transmitter

Coriolis Mass Flowmeters Product Types for Industry Selection

A Coriolis mass flow meter is an instrument designed to directly measure the mass flow rate of fluids. It operates independently of changes in temperature, pressure, viscosity, or density, while simultaneously outputting fluid density and temperature in real time.

Composed of a sensor and a transmitter, its operating principle is based on the Coriolis effect.

Key Advantages: Direct mass flow measurement (no pressure or temperature compensation required), high accuracy (typically $\pm0.1\% \sim \pm0.05\%$ for liquids and $\pm0.5\%$ for gases), multi-variable measurement (simultaneously outputs mass flow, volume flow, density, and temperature), zero straight pipe run requirements, and immunity to changes in fluid physical properties.

Main Limitations: High initial cost, relatively large pressure drop, susceptibility to external pipe vibration, and line size limitations for larger diameters.

To handle extreme conditions across diverse industrial applications—such as ultra-high pressure, cryogenic temperatures, severe corrosion, sanitary CIP/SIP cleaning, or large pipe sizes—various specialized product categories have been developed, differing in sensor construction, tube geometry, wetted materials, mounting options, and transmitter configurations.
