Disclosed embodiments include electromagnetic flow regulators for regulating flow of an electrically conductive fluid, systems for regulating flow of an electrically conductive fluid, methods of regulating flow of an electrically conductive fluid, nuclear fission reactors, systems for regulating flow of an electrically conductive reactor coolant, and methods of regulating flow of an electrically conductive reactor coolant in a nuclear fission reactor.

Systems, methods and apparatus for providing an electromagnetic flow controller. In one embodiment, an electromagnetic flow controller can have two substrates, a permanent magnet, and two electrical traces. One of the substrates may deflect away from the other substrate upon applying an electrical signal to at least one of the two electrical traces.

A first detection electrode that outputs a first flow rate signal and a second detection electrode that outputs a second flow rate signal, a differential circuit that outputs a differential flow rate signal obtained by obtaining a difference between the first flow rate signal and the second flow rate signal, an AC signal generation circuit that causes a first AC current to flow between the first detection electrode and the ground electrode and causes a second AC current with a reverse phase at the same frequency as that of the first AC current to flow between the second detection electrode and the ground electrode, and a diagnosis unit that diagnoses an abnormality of at least either of the first detection electrode or the second detection electrode based on a differential flow rate signal.
