Flowmeter, e.g. ultrasound or vortex flowmeter, comprises seal that is positioned between ultrasound waveguide and measuring tube

摘要

A flowmeter comprises a measuring tube, an ultrasound transducer, an ultrasound waveguide and a seal. The transducer connects outside the measuring tube to waveguide such that ultrasound waves generated by transducer are transferred to waveguide and, conversely, waves received by waveguide are transferred to transducer (2). The waveguide protrudes into the measuring tube.
