Functional principle

The magnetic-inductive inline flow meter FCMI

by TURCK is based on the Faraday principle.

A measuring tube permeating magnetic

field deviates the free charge carriers in the

targeted medium to the tube walls. Voltage is

created by electrical separation and picked

up by two laterally mounted electrodes. The

voltage quantity depends on the flow rate

i.e.flow if the magnetic field is known. Thus

the FCMI flow meter monitor reliably and

wear-free the flow of various different liquid

media which feature a determined minimum

conductivity.
