Title:
MEASUREMENT METHOD, APPARATUS AND DEVICE FOR ELECTROMAGNETIC FLOWMETER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/081956
Kind Code:
A1
Abstract:
An electromagnetic flowmeter detection method, an electromagnetic flowmeter detection apparatus, an electromagnetic flowmeter and a computer-readable storage medium. The method comprises: collecting a voltage signal generated during the operation of an electromagnetic flowmeter; monitoring the voltage signal to acquire a voltage signal of a predetermined period of time; and according to the voltage signal of the predetermined period of time, determining whether air enters a measuring pipe of the electromagnetic flowmeter. The cost of the electromagnetic flowmeter is reduced while realizing air detection in the measuring pipe.
