Flow Measurement Magnetic flow meters are made up of a transmitter and sensor that together measure flow. The flow meter’s sensor is placed inline and measures an induced voltage generated by the fluid as it flows through a pipe. The transmitter takes the voltage generated by the sensor and converts the voltage into a flow measurement and transfers the flow measurement to a control system. Faraday's Law 'Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force —a phenomenon called electromagnetic induction.' Wikipedia How to select a Magmeter When selecting the right Magnetic flow meter it is best to ask the following key questions What is the pipe size? Is the fluid water based or conductive? Is the fluid or slurry abrasive? What display is required - integral or remote? Output selection - analogue or digital? Flow rate - minimum and maximum? Process pressure - minimum and maximum? Process temperature - minimum and maximum? If the fluid is a chemical based one will it be compatible with the flow meter wetted parts? What installation considerations are there? Magnetic Flow meters for Conductive Liquids A magnetic flow meter (mag flow meter) is a volumetric flow meter which does not have any moving parts and is ideal for wastewater applications or any dirty liquid which is conductive, or water based. Magnetic flow meters will generally not work with hydrocarbons, distilled water, and many non-aqueous solutions. Magnetic flow meters are also ideal for applications where low-pressure drop and low maintenance are required. Faraday's Law The operation of a magnetic flow meter or mag meter is based upon Faraday's Law, which states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor. To apply this principle to flow measurement with a magnetic flowmeter, it is necessary first to state that the fluid being measured must be electrically conductive for the Faraday principle to apply. Magnetic flow sensors are sensitive to electrical noise which is present in most piping systems. In plastic piping systems, the fluid carries significant levels of static electricity that must be grounded for best magnetic flow meter performance. The obstruction to the flow is almost nil and therefore this type of meters can be used for measuring heavy suspensions, including mud, sewage and wood pulp. There is no pressure head loss in this type of flow meter other than that of the length of straight pipe which the meter occupies. They are not very much affected by upstream flow disturbances. They are practically unaffected by variation in density, viscosity, pressure and temperature. These meters can be used as bidirectional meters. The meters are suitable for most acids, bases, water and aqueous solutions because the lining materials selected are not only good electrical insulators but also are corrosion resistant. The meters are widely used for slurry services not only because they are obstruction less but also because some of the liners such as polyurethane, neoprene and rubber have good abrasion or erosion resistance. They are capable of handling extremely low flows. Displays are integral or an analogue output can be used for remote monitoring or data logging.
