EMERSON mass flow meters provide flow and density measurements for liquids, gases, and multiphase fluids, while ELITE Coriolis flow meters are designed to provide repeatable flow measurements to meet the requirements of various challenging environments and applications. Mass flow meters are a type of inferential flow meter that can be divided into two categories based on measurement: one is indirect measurement of mass flow rate, which simultaneously measures the volume flow rate and density value of the fluid, calculates the fluid mass by an operational amplifier, or simultaneously measures the volume flow rate, temperature, and pressure value of the fluid, and calculates the fluid mass by using the relationship between fluid density, temperature, and pressure; the second is direct measurement of mass flow rate, where fluid measurement directly reflects the mass flow rate value and is independent of changes in parameters such as fluid temperature, pressure, and density.

EMERSON flow meter features:
Process data, repeatable, suitable for a wide range of flow and process conditions.
Capable of directly measuring mass flow rate and density online, as well as measuring volumetric flow rate and temperature, with one device and multiple functions.
No movable parts, thereby reducing maintenance costs.
No rectification is required, nor is there a need for specialized straight pipe sections, thus simplifying installation and reducing expenses.
Can provide advanced diagnostic tools for instruments and processes
