This article presents a method of measuring flux of gas and liquid in pipes, It uses a turbine flow sensor based on magnetic-suspension bearing. The running state of the magnetic-suspension turbine under designed conditions is described. The characteristic of the magnetic-suspension bearing and its differences from the general bearing are presented. The results of experiment show that when the method is adopted, the minimum flow declines very much, and the upper limit of measuring of flux is improved. Therefore the range for measuring is widened.
