Charun Electromagnetic Flow Meter-02

We offer Electromagnetic Flow Meter-02. it is called as magmax virtually approaches the ideal flow meter suitable for wide range of liquid flow measurements even with very low conductivities. the meter offers no resistance to flow hence the pressure drop is almost negligible. the measurement being based on faraday`s law of electromagnetic induction, is independent of viscosity, density, pressure & temperature of flowing medium. the measurement is not affected by solid impurities as long as the min. conductivity of 5 ms /cm is available. it is a true volumetric flow measurement. we offer various materials of construction for meter lining & electrodes to cover majority of corrosive liquids.
principle advantages
use of pulsed dc magnetisation & auto zero technique offers excellent long term zero stability measurement is independent of velocity profile across the diameter of the pipe- linemeasurement results are independent of density, viscosity, pressure, temperature, solid - impurities & conductivity variations [above 5 ms /cm]no additional pressure drop across the meter which relieves the process designer while sizing his pumping requirementssimple to install as no special precautions of straight pipe lengths requiredcompatible with virtually all corrosive / non - corrosive liquidsprotection class offered ip 65reasonably higher ratio of return on investment to investment
principle of operation
the method of flow measurement is based of faraday`s law of electromagnetic induction. when a conductor moves within a magnetic field, voltage is induced in it which is proportional to the velocity of conductor. in this case the conductor is flowing media. the equation is as below
e = b.v.d wheree = induced voltage [proportional to velocity]b = magnetic flux densityv = mean velocity of the mediad = distance between the sensing electrodes
for a given size of flow tube & compatible amplitier the flux density 'b� is constant, the distance between the electrodes is constant. hence, the induced voltage is proportional to the velocity of the flowing media. thus, the unit can be calibrated in terms of volumetric flow rate by knowing the cross - sectional area of the tube.
