Abstract

Based on the analysis of the magnetic circuits of the electromagnetic flow transducers with uniform circular pipe, locally shrunk circular pipe and locally shrunk rectangular pipe, the sensitivities of the different designs were compared. The design with locally shrunk rectangular pipe was adopted, the efficiency of the magnetic circuit was effectively enhanced, the sensitivity of the transducer was increased. A prototype flow meter was developed based on the proposed design and was tested. The experiment result shows that the prototype has the precision better than 0.5% over the specified measurement range. When powered with a high power lithium battery set, the prototype can work for more than 3 years continuously. The feasibility of the proposed design was proved.
