The measuring system for measuring density and/or a mass flow rate, especially also a total mass flow totalled over a time interval, of a medium, at least at times, flowing in a pipeline, especially with a mass flow rate of more than 1000 t/h, especially a gas, a liquid, of a powder or other flowable material, wherein this measuring system, which is especially embodied as an in-line measuring device and/or a measuring device in compact construction, comprises a measuring transducer comprising:
- a measuring transducer of vibration type for registering at least one physical measured variable of a flowable medium conveyed in a pipeline and/or for producing Coriolis forces serving for registering a mass flow rate of a flowable medium conveyed in a pipeline, said measuring transducer comprising:
- a transducer housing, of which an inlet-side, first housing end is formed by means of an inlet-side, first flow divider including eight, mutually spaced apart flow openings and an outlet-side, second housing end is formed by means of an outlet-side, second flow divider including eight mutually spaced apart flow openings;
- a tube arrangement including, for conveying flowing medium,
- a bent first measuring tube opens with an inlet-side, first measuring tube end into a first flow opening of the first flow divider, and opens with an outlet-side, second measuring tube end into a first flow opening of the second flow divider,
- a bent second measuring tube, which is especially at least sectionally parallel to the first measuring tube, opens with an inlet-side, first measuring tube end into a second flow opening of the first flow divider and with an inlet-side, first measuring tube end into a second flow opening into of the second flow divider,
- a bent third measuring tube opens with an inlet-side, first measuring tube end into a third flow opening of the first flow divider and with an outlet-side, second measuring tube end into a third flow opening of the second flow divider,
- a bent fourth measuring tube, which is especially at least sectionally parallel to the third measuring tube, opens with an inlet-side, first measuring tube end into a fourth flow opening of the first flow divider, and with an outlet-side, second measuring tube end in to a fourth flow opening of the second flow divider,
- a bent fifth measuring tube, which is especially at least sectionally parallel to the fifth measuring tube, opens with an inlet-side, first measuring tube end into a sixth flow opening of the first flow divider of the first flow divider and with an outlet-side, second measuring tube end into a fifth flow opening of the second flow divider,
- a bent sixth measuring tube, which is especially at least sectionally parallel to the fifth measuring tube, opens with an inlet-side, first measuring tube end into a sixth flow opening of the first flow divider, and with an outlet-side, second measuring tube end into a sixth flow opening of the second flow divider,
- a bent seventh measuring tube opens with an inlet-side, first measuring tube end into a seventh flow opening of the first flow divider, and with an outlet-side, second measuring tube end into a seventh flow opening of the second flow divider, and
- a bent eighth measuring tube, which is especially at least sectionally parallel to the seventh measuring tube, opens with an inlet-side, first measuring tube end into an eighth flow opening of the first flow divider, and with an outlet-side, second measuring tube end into an eighth flow opening of the second flow divider;
- and
- an electro-mechanical exciter mechanism for producing and/or maintaining bending oscillations of each of said first, second, third, fourth, fifth, sixth, seventh, and eighth measuring tubes, especially oscillations corresponding to a natural oscillatory mode the tube arrangement;
- and
- a transmitter electronics, said transmitter electronics being electrically coupled with the measuring transducer, and said transmitter electronics serving for activating the measuring transducer, especially its exciter mechanism, and for evaluation of oscillation signals delivered by the measuring transducer.
