求の範囲第(2)項に記載のコリオリカ式流量計。[Scope of claims for utility model registration] (1) A pipe body with both ends fixed and through which fluid flows;
The driving means for driving the central part of the tubular body in a direction perpendicular to the tubular body, and the detecting means for detecting the Coriolis force generated in a direction perpendicular to the driving angular velocity vector and the flow velocity vector due to this driving are almost the same. A Coco Orica flowmeter characterized in that it has a plurality of the above characteristic means, one set is used in normal measurement, and it is possible to switch to the other set. (2) The Coriolis type flowmeter according to claim (1) of the utility model registration, characterized in that the detection means is a detection means and means for sensing temperature, etc. necessary for flow rate correction. (3) The driving means, the detection means, and the sensing means are characterized by superimposing an electric signal outside the normal measurement range, detecting the stop of this electric signal, and switching to other than the plurality of corresponding means. The Coriolis type flowmeter according to claim (2) of the utility model registration claim.
