Applications :

A velocity or volumetric flow metre that operates in accordance with Faraday's law of electromagnetic induction, which stipulates that a voltage will be produced when a conductor flows through a magnetic field, is known as a magmeter. Only conductive fluids can have their flow rate detected by magmeters. The operation of early magmeter designs required a fluidic conductivity of 1 to 5 microsiemens per centimetre.

A millivolt signal represents the voltage that forms at the electrodes. At or close to the flowtube, this signal is often transformed into a standard current output (4–20 mA) or frequency output (0–10,000 Hz). Direct connection to a dispersed control system is possible with intelligent magnetic transmitters with digital outputs. 

Direct or alternating current can be used to power the magmeter's coils (Figure 2). Line voltage is applied to the magnetic coils when ac excitation is utilised. As a result, the flow signal will also resemble a sine wave when the flow is constant. The wave's amplitude and velocity are inversely proportional. In addition to the flow signal, noise voltages can be induced in the electrode loop. Out-of-phase noise is easily filtered, but in-phase noise requires that the flow be stopped (with the pipe full) and the transmitter output set to zero. The main problem with ac magmeter designs is that noise can vary with process conditions and frequent re-zeroing is required to maintain accuracy.
