Title:
ULTRASONIC FLOW RATE METER AND METHOD OF USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/097684
Kind Code:
A1
Abstract:
This invention provides an ultrasonic flow rate meter that enables a flow rate measurement tube to be replaced easily and prevents the flow rate measurement tube from falling off. This ultrasonic flow rate meter 20 measures the flow rate of a fluid on the basis of a difference in transmission time of ultrasonic waves that are sent and received between ultrasonic sensors 21, 22. The ultrasonic sensors 21, 22 transmit ultrasonic waves alternately through a flow rate measurement tube 11. A measurement tube holder 42 has a measurement tube housing section 43 that covers the flow rate measurement tube 11 such that both end sections of the flow rate measurement tube 11 are exposed. A first sensor cover 51 houses the ultrasonic sensor 21 and is coupled to a first end 42a of the measurement tube holder 42. A second sensor cover 61 houses the ultrasonic sensor 22 and is coupled to a second end 42b of the measurement tube holder 42. At least one of the first sensor cover 51 and the second sensor cover 61 is detachably attached to the measurement tube holder 42.
