Questions about electromagnetic flowmeters, seeking advice

The pipe is filled with medium, but the medium does not flow – how should an electromagnetic flowmeter display this? ?
It should show as zero, right? If it is a cumulative value, the number remains unchanged
According to the principle of electromagnetic flowmeters, an electromotive force can be generated and flow can be detected only when the fluid flows and cuts through the magnetic field lines
Not only electromagnetic flowmeters, but all flowmeters work in this way: when the fluid does not flow, it is as if the fluid has not passed through the sensing element, which is equivalent to having an empty pipe. . .
It shows as zero. With electromagnetism, you should know the principle behind its measurement – when the medium doesn’t move, no electromotive force is generated, and without an electromotive force, there is no flow
