Coriolis type mass flow meter has a tensioning adjustment mechanism that can be set to match fluid properties so that asymmetries or anisotropies in the measurement flow medium caused by interference vibrations are suppressed

摘要

Method for determination of the mass flow rate of a fluid medium (100) through a measurement pipe (2) that is contained and supported by a support pipe (3, 4) that is used to excite vibrations in the measurement pipe so that Coriolis mass flow measurements can be made. To prevent asymmetries or anisotropies in the measurement flow medium the measurement arrangement is tensioned to match the properties of the fluid medium either prior to, or during measurements. An Independent claim is made for a Coriolis type mass flow measurement device wherein the support pipe for the measurement pipe is in contact with a tensioning and adjustment device (7) with which a defined tensile force can be applied to balance out asymmetries or anisotropies.
