3. Working Principle

The electromagnetic flow meter operates based on Faraday’s Law of Electromagnetic Induction. When a conductive liquid flows through a magnetic field, it induces a voltage proportional to the flow velocity. Electrodes inside the flow tube detect this voltage, which is then processed by the transmitter to determine the flow rate.

Formula: E=B×V×DE = B \times V \times D Where:

- E = Induced Voltage
- B = Magnetic Field Strength
- V = Fluid Velocity
- D = Inner Diameter of Pipe

4. Assembly Process

Sensor Housing: Fabricated using SS316 or carbon steel.
Electrode Placement: Positioned at strategic points for optimal detection.
Lining Installation: PTFE or rubber lining for chemical resistance.
Electronic Unit Mounting: Processor and transmitter integrated.
Display Unit Fixing: LCD/OLED display with user interface.

5. Installation Process

Ensure correct pipe alignment with minimal turbulence.
Install in a full pipe to avoid air gaps.
Maintain minimum straight pipe length before and after the meter:
- Upstream: 10x diameter
- Downstream: 5x diameter
Properly ground the meter for accurate readings.
Avoid installation near strong electromagnetic fields.
Use flange gaskets to prevent leaks.
