Coriolis-flow measuring device operating method for determining e.g. mass density of medium, involves determining correction data to make amplitude correction in such manner that amplitude values for determination of flow are drawn

摘要

The method involves placing a temperature sensor (2) at a position of a coriolis flow measuring pipe (1) or flow measuring device that is utilized for measuring a local temperature. A temperature distribution field is computed from a temperature distribution theorem. Correction data are determined from a temperature field data to make an amplitude correction in such a manner that relevant temperature effect adjusted amplitude values for determination of the flow are drawn. An independent claim is also included for a coriolis-flow measuring device with a flow measuring pipe.
