  • On-site calibration method of ultrasonic flowmeter based on acoustic velocity detection
    Patent number: 12158364
    Abstract: An on-site calibration method of an ultrasonic flowmeter based on acoustic velocity detection includes: collecting layered water temperature measured values of respective acoustic channels of the ultrasonic flowmeter, to obtain abnormal data of the layered water temperature measured values; and based on an abnormal acoustic channel corresponding to the abnormal data, calibrating the abnormal acoustic channel of the ultrasonic flowmeter through acquiring a layered line flow velocity.
