Abstract:
A clamp-on ultrasonic flowmeter comprising a first sensor assembly and a second sensor assemblywhich are positioned at a given distance from each other either along one straight surface line of a pipe conducting a fluid to be measured or along a first straight surface line of the pipe and a diametrically opposed, second straight surface line, respectively, and attached by means of a first pipe strap and a second pipe strap, respectively, and wherein said first sensor assembly and said second sensor assembly are identical in construction and each comprise: a flat bracket adjacent to the pipe and having a longitudinal center line and a tubular portion integrally formed thereon; a sensor inset longitudinally guided in the tubular portion and containing an ultrasonic transducer with a transducer element; a sensor cap which is put over the tubular portion, is secured to the tubular portion by means of a snap fastening releasable by rotation, and comprises a spring which forces the sensor inset against the pipe; and a strap-tightening device fixed in the bracket approximately in the middle of the longitudinal center axis thereof.
