The operating principle of Magnetic flow meters is based upon Faraday's Law of electromagnetic induction, "It state that a voltage will be induced in a conductor moving through a magnetic field".
E = kBDV
Where E = Induced Voltage, B = Strength of the magnetic field, D = Conductor Width, V = Velocity of the conductor
The magnitude of the induced voltage E is directly proportional to the velocity of the conductor width D, and the strength of the magnetic field B. Liquid acts as a conductor as it flows through pipes. This Flowmeters find varied applications where the flowing medium is difficult to handle.
Major advantage of these flowmeters are : Zero pressure drop, No moving part and highest accuracy level at most affordable cost.
Some of the major application can be described below :
Effluent Treatment plant, Sewage Treatment plant, Water supply Schemes, Pulp and Papers, Sugar industries and Distilleries, Steel and Aluminium, Chemical / Pharmaceuticals, Food and Drugs etc.
Tolerates High percentage of suspended solids Sludge, slurries, minerals, paper, sewage - flows with high level of solids which can not be measured other type of meters. Obstruction less measurements Nothing projects into the flow stream, no head loss, no parts to maintain.
Suitable for corrosive liquid Acids, caustic and corrosive additives are isolated from the meter pipe by inert linings and compatible electrodes. Suitable for all types of electrically conductive liquids. Liquid where conductivity is of sufficient level to induce measurable
