Title:
ULTRASONIC FLOWMETER
Document Type and Number:
Japanese Patent JP2023014538
Kind Code:
A
Abstract:
To provide an ultrasonic flowmeter which makes it less frequent to suffer from dust jams and pressure loss compared to traditional ones and which can mitigate measurement errors due to elbow piping.SOLUTION: An ultrasonic flowmeter comprises: a measurement pipe 1 having a circular tube shape area 101 the profile in a direction perpendicular to an axial direction of which is configured to be a circular tube shape and to which fluid that is a measuring object flows, a rectangular tube shape area 103 the profile in a direction perpendicular to the axial direction of which is configured to be a rectangular tube shape, and a loft shape area 104 that is configured to be a loft shape for connecting the circular tube shape area 101 to the rectangular tube shape area 103; an ultrasonic sensor 2 arranged on an upstream side in the rectangular tube shape area 103 of the measurement pipe 1 and performing ultrasonic transmission/reception to/from the downstream side; and a an ultrasonic sensor 3 arranged on the downstream side in the rectangular tube shape area 103 of the measurement pipe 1 and performing ultrasonic transmission/reception to/from the upstream side.SELECTED DRAWING: Figure 1
