The FK-LDG-A100D operates according to Faraday’s Law of Electromagnetic Induction.
Two electromagnetic coils installed on the upper and lower sides of the measuring tube generate a constant or alternating magnetic field.
When conductive liquid flows through the magnetic field:
-
An induced electromotive force (E) is generated.
-
The induced voltage is proportional to the flow velocity.
-
Two electrodes mounted on the tube wall detect the voltage.
-
The converter processes the signal to calculate flow rate.
Induced Voltage Equation:
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
Because the induced voltage is proportional to flow velocity, accurate flow measurement can be achieved as long as the liquid conductivity exceeds the minimum required level.
The processed signal provides:
