An electric potential is developed when a conductor is moved across the magnetic field. In most electrical MACHINERY the conductor is a wire. The principle is equally applicable to a moving, electrically conductive liquid. The primary device of commercial magnetic meters consist of STRAIGHT cylindrical electrically insulated tube with a PAIR of electrodes nearly flush with the tube walls and located at opposite end of a tube DIAMETER. This device is limited to electrically conducting liquids. The magnetic meter is particularly suited to MEASUREMENT of slurries and dirty fluids.
