ABSTRACT:
In a housing two ultrasonic measuring transducers are arranged opposite of the two end faces of a test tube. The test tube providing a measuring section penetrates a separating wall and interconnects two distribution chambers of the housing. The fluid to be measured flows through the test tube and influences the transit time of the ultrasonic impulses released and received by the measuring transducers. The test tube provides a constant cross-section of metallic material along the length of the measuring section. The connection between the test tube and the separating wall consists of a nonmetallic material, thus preventing echoes which may penalize the measuring accuracy.
