Ultrasonic flow meter, has flow channel with measuring section extending along longitudinal direction of flow channel, and inlet and discharge sections led into measuring section at distance from each other

摘要

The meter (1) has a flow channel (3) with a measuring section (6) that extends along longitudinal direction of the flow channel. Inlet and discharge sections (5, 7) are led into the measuring section at distance from each other. Ultrasonic elements (8, 9) of a pair of ultrasonic transducers are arranged at ends of the measuring section that extends along a straight line. The ultrasonic elements are arranged opposite to each other and tightly seal the ends of the measuring section, where cross section of the measuring section is larger than cross section of the inlet and/or discharge sections.
