Electromagnetic flowmeter measures flow rate by using Faraday's law of electromagnetic induction.

• Electromagnetic flowmeter is based on the principle of Faraday's law of electromagnetic induction.

• It consists of a flow tube, electrodes, and a magnetic field.

• When a conductive fluid flows through the flow tube, it generates a voltage proportional to the flow rate.

• The electrodes detect the voltage and the magnetic field ens...read more

Interacting systems have feedback loops and can influence each other's behavior, while non-interacting systems operate independently.

• Interacting systems have mutual dependencies and can affect each other's inputs, outputs, or behavior.

• Non-interacting systems operate independently and do not have any influence on each other.

• Interacting systems often involve feedback loops where the output of one system affects the input...read more
