How to Use Coriolis Mass Flowmeters

Coriolis mass flowmeters measure the mass flow of liquids, such as water, acids, caustic, chemicals, and gases/vapors. Because mass flow is measured, the measurement is not affected by fluid density changes. Coriolis mass flowmeters can measure flow extremely accurately so they are often used to measure high value products or the introduction of fluids that affect the production of high value products. 

Be particularly careful when using Coriolis mass flowmeters to measure gas/vapor flows because flow rates tend to be low in the flow range (where accuracy is degraded). Also, in gas/vapor applications, large pressure drops across the flowmeter and its associated piping can occur so special care should be taken to design the piping immediately upstream and downstream of the flowmeter to reduce its pressure drop in the system.
