Myth: Coriolis Meters are Easily Affected by Vibration

An often heard assumption about a Coriolis meter is that it is easily and regularly affected by external vibrations, and for that reason is not a reliable flow measurement technology.  I’m here to tell you, that it is just not true.

A simple explanation of the working principle of a Coriolis meter is that a tube is made to vibrate at a specific frequency and when the fluid flows through the tube the frequency of vibration will change.  This change in frequency is directly related to the mass of the fluid going through the tube and thus the mass flow measurement is made. The important bit here is that there is an induced vibration frequency of the tube.
