Applications :

According to Faraday's rule of electromagnetic induction, which states that a voltage will be induced when a conductor moves through a magnetic field, electromagnetic flow metres (also known as magmeters) are a form of velocity or volumetric flow metre. Only the flow rate of conductive fluids may be detected using magmeters. A fluidic conductivity of 1 to 5 microsiemens per centimetre was the minimum requirement for the operation of early magmeter designs. 

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. The lead wire should be insulated and twisted if the transmitter is remote since the magmeter signal is weak.

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 the electrode loop, noise voltages can also be created in addition to the flow signal. Filtering out-of-phase noise is simple, but for in-phase noise, the transmitter output must be adjusted to zero when the flow is stopped (and the pipe is still full). The fundamental issue with ac magmeter designs is that noise can change depending on the circumstances of the process, and regular re-zeroing is necessary to maintain accuracy.
