Measuring Principle
he FK-FMC800 operates based on Faraday’s Law of Electromagnetic Induction.
Two electromagnetic coils generate a magnetic field perpendicular to the flow direction. When conductive liquid flows through the magnetic field, an induced electromotive force (E) is generated between two electrodes installed on the tube wall.
The induced voltage is proportional to:
-
Flow velocity (V)
-
Magnetic induction density (B)
-
Inner diameter of measuring tube (D)
The equation is:
E = K × B × V × D
Where:
-
E – Induced electromotive force
-
K – Meter constant
-
B – Magnetic induction density
-
V – Average flow velocity
-
D – Inner diameter of measuring tube
The induced signal is transmitted to the converter for analog and digital signal processing. The display shows both:
-
Instantaneous flow rate
-
Totalized (accumulated) flow
The measured liquid must have conductivity higher than the minimum threshold specified in the technical parameters.
