What is an electromagnetic flowmeter?

A device that measures fluid flow using Faraday's Law of electromagnetic induction.

What fluids can it measure?

Conductive liquids only (e.g., water, slurries, acids). It cannot measure hydrocarbons or gases.

Does it work with full or empty pipes?

The pipe must be full; accuracy drops if the pipe is partially empty.

How is installation done?

Install with sufficient straight pipe runs upstream/downstream, away from pumps or bends.

What affects measurement accuracy?

Affected by fluid conductivity, air bubbles, solids, or improper grounding.

How is it calibrated?

Typically calibrated at the factory; field verification can be done with a magnetic field test.

How to handle zero drift?

Perform zero adjustment with the pipe completely full and the fluid stationary.

What maintenance is required?

Periodic inspection of electrodes, liners, and grounding; keep the electrode surfaces clean.
