    • Do not open the housing without authorization. The degree of protection of the flowme- ter FLUXUS G704 A2, G704 is given only if the cover of the housing is tightly screwed. • Keep the transducers clean. Manipulate the transducer cables cautiously. Avoid ex- cessive cable bend.

  • Page 25: Flowmeter

    4 Flowmeter Flowmeter Measuring Principle The flow of the medium is measured by ultrasonic signals using the transit time differ- ence method. Ultrasonic signals are emitted by a transducer installed on one side of a pipe, reflected on the opposite side and received by a second transducer. The signals are emitted alter- natively in and against the flow direction.
