This guide is the basic reference tool for all ONICON FT-3500 Electromagnetic Flow Meters. If you have not purchased all
of the options, there will be references in this manual which are not applicable to your meter(s).
1.2 TYPICAL INSERTION ELECTROMAGNETIC FLOW METER
Faraday’s Law of electromagnetic induction states that a voltage will be induced in a conductor when it passes through a
magnetic eld, and the induced voltage will be directly proportional to the velocity of the conductor.
ONICON FT-3500 Electromagnetic Flow Meters generate pulsating magnetic elds that are used to induce a voltage into
the conductive uid owing through the pipe. Electrodes located on the ow meter sensor head measure the induced
voltage. Circuitry within the remote transmitter electronics enclosure then converts the voltage to digital and analog
signals and network communication that convey ow rate, total volume, and thermal energy.
