PROBLEM TO BE SOLVED: To provide a piping structure for the upper-flow pipe and the lower-flow pipe of a Coriolis flowmeter, capable of minimizing the influence due to piping stress, and of generating hardly a span shift of the zero point and the span shift of an instrument error, even if an external force is applied onto the upper and lower-flow pipes and a flow meter body. SOLUTION: Respective fellow one-portions of the upper flow pipe 5 and the lower flow pipe 6 extended from the flowmeter body 4 of the Coriolis flowmeter 1 are approached each other, and the approached portions are integrated into one by using a piping support member 7. Other pipe axes of paired pipes in sides of line pipes 2, 3 are made to conform, among of the pipe axes of the upper flow pipe 5 and the lower flow pipe 6, and other pipe axes of paired pipes in sides of the flowmeter main body 4 are also conformed. Bolts 20 and nuts 21 are tightened in three points to fix the flowmeter body 4, when fixing the flowmeter body 4 onto a frame 12. COPYRIGHT: (C)2007,JPO&INPIT
