Electromagnetic flowmeters use Faraday's law to determine the flow of liquid in the pipeline. As a result, the flow of the conductive liquid through the magnetic field causes the electrodes located on the wall of the flow tube to sense a voltage signal. The voltage generated is proportional to the movement of the flowing liquid. In other words, the faster the fluid flows, the greater the voltage generated. Therefore, the electromagnetic flowmeter processes the voltage signal to determine the liquid flow rate.
The following are the shortcomings or disadvantages of electromagnetic flowmeters:
It needs power to run.
Electronic components used in electromagnetic flowmeters are more susceptible to damage.
The maintenance of electromagnetic flowmeter requires special equipment. In addition, it requires skilled technicians. This increases the cost of maintaining the instrument.
The following are the advantages or advantages of electromagnetic flowmeters:
It does not have any moving parts, so they are minimally affected by the turbulent flow related to viscosity or density.
The electromagnetic flowmeter will not obstruct the flow. Therefore it can be used for clean, hygienic, dirty, corrosive and abrasive liquids.
Electromagnetic flowmeter measurement is not affected by flow conditions such as laminar flow or turbulent flow.
EM flowmeter is used as a volume flow measuring instrument. In addition, it can also be used to measure the temperature, viscosity, density and conductivity of the medium.
Electromagnetic flowmeter provides better performance and reliability.
All of our full-bore electromagnetic flowmeters provide a complete solution for continuous measurement or batch control, suitable for a variety of applications from water treatment to sanitary food and beverage or pharmaceutical applications.
