Title:
ULTRASONIC FLOW RATE MEASURING DEVICE AND ULTRASONIC FLOW RATE MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/162284
Kind Code:
A1
Abstract:
Provided are an ultrasonic flow rate measuring device used for measuring the flow rate of a fluid flowing through a pipe and a highly accurate ultrasonic flow rate measuring method for the ultrasonic flow rate measuring device, the ultrasonic flow rate measuring device being easy to be attached to the pipe body.
The ultrasonic flow rate measuring device measures the flow rate of a medium flowing through a pipe body in such a way that: when one of a plurality of ultrasonic vibration sending and receiving means functions as a vibration sending means and sends an ultrasonic vibration, another one functions as a vibration receiving means and receives the ultrasonic vibration; and when the another one functions as the vibration sending means and sends an ultrasonic vibration, the one functions as the vibration receiving means and receives the ultrasonic vibration. An ultrasonic propagation control means for controlling the propagation of ultrasonic waves is equipped between the ultrasonic vibration sending and receiving means functioning as the vibration sending means and the vibration receiving means. The ultrasonic flow rate measuring device can also be easily attached to a pipe body.
