When a flowing conducting fluid is subjected to a diagonally magnetic field, the flowing conducting fluid cuts the magnetic field and sources a voltage to be stimulated. This induced voltage is comparative to the liquid swiftness, i.e., flow rate.
Construction
A conducting fluid is flowing through a non-magnetic and non-conducting pipe, that flow rate is to be calculated. Two electrodes are linked in opposite sides of pipe carrying the conducting fluid. These electrodes get in touch with flowing conducting fluid. The pipe is surrounded by an electromagnet that creates a magnetic field.
Benefits
These Magnetic Flow Meters does not cause barrier to flow and hence cause no drop in pressure. For ability, it does not matter if the flow is laminar or turbulent. It gives exact results. Its constancy is high, i.e., it gives a standard performance for an extensive period of time. It can handle greasy materials and liquids comprising of suspended solids. The dimension is self-regulating of temperature, pressure, viscosity and density.
Working Principle
The theory of operation for the magnetic flow meter is based on the Faraday’s Law of Electromagnetic Induction.
When a conductive fluid flows through the magnetic field, a small voltage (u) is stimulated. This voltage is relative to the speed of the flow and is precisely measured by two stainless steel electrodes mounted opposite each other inside the metering pipe. The two electrodes are linked to an advanced electronic input circuitry that processes the signal and in turn feeds it to the microprocessor inside the electronics module. The microprocessor then computes the volumetric flow and directs the various outputs on the terminal board.
