1. An electromagnetic flowmeter for monitoring a flow rate of a fluid, the electromagnetic flowmeter comprising:
a conduit for facilitating a flow of the fluid;
an electromagnetic assembly coupled to the conduit and adapted to generate a magnetic field inside the conduit;
a ring assembly to modify a velocity profile of the fluid arranged on an inner liner wall of the conduit, the ring assembly comprising one or more sliders attached to a ring and extending substantially parallel to a central axis of the ring, wherein a position of the ring assembly is adjustable along the inner liner wall of the conduit at a predetermined distance to varyingly reform the velocity profile of the fluid based on the position of the ring assembly, and wherein the one or more sliders facilitate sliding of the ring against the inner liner wall of the conduit; and
a pair of electrodes mounted to the conduit and disposed downstream of the ring assembly, the pair of electrodes detecting an induced voltage generated within the reformed fluid due to the magnetic field, wherein the flow rate of the fluid is determined based on the induced voltage.
