摘要： The invention relates to a sensor for detecting at least one physical measurable variable of a flowable medium guided in a tube conduit and/or for producing Coriolis forces which serve to detect the mass flow rate of a flowable medium guided in a tube conduit. The sensor comprises a sensor housing (7
1 ), a housing end on the inlet side being defined by a splitter (20
1 ) on the inlet side which has exactly four respective interspaced flow openings (20
1A , 20
1B , 20
1C , 20
1D ) and a housing end on the outlet side being defined by a splitter (20
2 ) on the outlet side which has exactly four respective interspaced flow openings (20
2A , 20
2B , 20
2C , 20
2D ), and exactly four straight measuring tubes (18
1 , 18
2 , 18
3 , 18
4 ) for guiding the flowing medium which tubes are connected to the splitters (20
1 , 20
2 ) to give fluidically parallel flow paths. The respective measuring tube end on the inlet side of each of the four measuring tubes leads to one of the flow openings (20
1A , 20
1B , 20
1C , 20
1D ) of the splitter (20
1 ) on the inlet side and the respective measuring tube end on the outlet side leads to one of the flow openings (20
2A , 20
2B , 20
2C , 20
2D ) of the splitter (20
2 ) on the outlet side. The sensor further comprises an electro-mechanical exciter arrangement (5) for producing and/or maintaining mechanical vibrations of the four measuring tubes (18
1 , 18
2 , 18
3 , 18
4 ), the exciter arrangement being designed such that it can be used to excite the paired measuring tubes to perform respective counter-phase flexural vibrations in a respective common imaginary plane of vibration (XZ
1 , XZ
2 ). The sensor according to the invention is especially suitable for measuring a density and/or a mass flow rate of a medium which flows at least temporarily inside a tube conduit at a mass flow rate of more than 2200 t/h.
