Experimental Investigation on Zero Drift Effect in Coriolis Mass Flowmeters

• Abstract:

  It is claimed that Coriolis mass flowmeter (CMF) can accurately measure the mass flow-rate without being effected by temperature. However, evidences from practical industry applications show that sometimes CMFs still suffer so-called "zero drift (ZD) effect": the origin of the flowmeter (reading at zero flow) varies as temperature changing. In this paper, series of experiments are carried out to systematically examine and analyze the performance of a Narrowed-U-CMF in a temp- changing environment. Based on the results of these experiments, possible reasons causing the ZD effect are analyzed, which provides a base for further solutions of the ZD effect.
