Ultrasonic flow meter

摘要

This ultrasonic flow meter is provided for measuring flow volume by determining the flow rate of a liquid from the difference in propagation times of ultrasonic waves in both directions between measuring units by providing measuring units having transducer at an interval in the lengthwise direction on a measuring pipe through which liquid flows. A pair of mounting members are provided in a lower case of a case serving as a base at an interval wider than that of measuring units. The measuring pipe is held by respective retaining indentations to the outside in the axial direction of measuring units by facing a left mounting member and a right mounting member that compose the mounting members. In addition, an insulating material is filled into the case so as to cover the measuring units and the measuring pipe.
