ABSTRACT:
A magnetic metering system comprising a transversely magnetized cylinder carrying a radially extending pointer and mounted for axial rotation between a diametrically disposed pair of biasing magnets and a diametrically disposed pair of solenoid coils, and rotation compensating means disposed between the biasing magnets and the solenoid coils for providing the cylinder and pointer with an angular movement proportional to changes in a current flowing through the solenoid coils.
