LF654 /LF622
Electromagnetic Flowmeter
1/2" to 18" (15 to 450 mm)
Introduction
The electromagnetic flowmeter uses Faraday’s Law of
electromagnetic induction to measure the process flow.
The device consists of two units: a detector, through
which the fluid to be measured flows and in which
low-level signals proportional to flow rates are
obtained; and a converter, which supplies excitation
current to the
