1 Advanced instrumentation solutions crafted with highest precision

2 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 standardised output signal or displayed in appropriate engineering unit. The flux density of the electromagnetic field in a given Flowmeter and the distance between the electrodes are constant. Therefore, the induced voltage is only a function of liquid velocity. E = KxBxvxD where E : Induced voltage K : Flow tube constant B : Magnetic field strength v : Mean flow velocity and D : Electrode spacing Volume flow is calculated by equation 2 Q = vxd xb/4 MagFlow 641 Working Principle Electromagnetic Flowmeters are based on Faraday's Law of Electromagnetic Induction. In an Electromagnetic Flowmeter, the 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 to its velocity. This induced voltage is ExDxB Therefore, Q = KxBx4 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 measured 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. MagProbe 645 EcoMag 642 MagBP 644 2
