IPC: G01F1/66
Filed: 2002-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ultrasonic wave flowmeter capable of keeping a high precision measurement condition even if the shape of a flow tube changes on upstream side or downstream side of an ultrasonic wave transmission/reception apparatus.  <P>SOLUTION: At least one part where the cross section of the flow tube is not circular is provided on the upstream side or downstream side of the ultrasonic wave transmission/reception apparatus. A tube fixing part is provided to keep the flow tube straight on a farther upstream side or downstream side.
