1. A system comprising:
a pipe having an outer circumferential surface and an inner circumferential surface, wherein the inner circumferential surface defines an orifice;
a multiphase fluid disposed within the orifice of the pipe; and
a measurement unit connected to the pipe, the measurement unit comprising:
a cylindrical structure disposed within the orifice of the pipe, submersed in the multiphase fluid, and having a first end and a second end, wherein the first end is opposite the second end along an axis;
a first magnet connected to the first end of the cylindrical structure;
a second magnet connected to the second end of the cylindrical structure;
a first coil wound around the outer circumferential surface of the pipe in a location corresponding to a location of the first magnet disposed within the orifice; and
a second coil wound around the outer circumferential surface of the pipe in a location corresponding to a location of the second magnet disposed within the orifice.
