OPERATIONS

Electromagnetic Flowmeters are based on Faraday’s law of Electromagnetic Induction.
In a Electromagnetic Flowmeter, magnetic field is generated by a set of coils. As the conductive liquid passes through the electromagnetic field, an electric voltage is induced in the liquid, which is directly proportional its velocity. This Induced voltage is perpendicular to both the liquid flow direction and the electromagnetic field direction. The voltage sensed by the electrodes Is further processed by the transmitter to give standardized output signal or displayed In appropriate Engineering Units on LED Display.
The flux density of the electromagnetic field In a given Flow meter and the
distance between the electrodes are constant, therefore, the induced voltage is only a function or liquid velocity.

 

E • K.B.v.D where E :Induced voltage
                                   K :flow Tube Constant
                                  B : Magnetic field velocity
                                               v : Mean flow velocity              
                         and D :Electrode Spacing

Volume flow Is calculated by equation :
         Q ;v.D² π/4
 
Therefore, Q = E.D. π
                               K.B.4

The induced voltage is not affected by the physical properties of liquid like
temperature. Viscosity pressure density and conductivity as long as conductivity of the measure liquid is above minimum threshold level. For reliable measurement the pipe must be completely full of liquid.

The electromagnetic field coil assembly is excited by pulsed DC technique,
which eliminates the interfering noise and provides automatic zero correction.
