The FMC nutating disc meter
With this flow meter, the liquid must flow through a measuring chamber.
A disc is arranged in the measuring chamber in such a way that it is displaced into
a nutating movement by the liquid flowing through.
A magnetic pin is arranged in the middle of this disc that then makes a circular move-
ment.
The magnetic pin completes one revolution when the measuring chamber is filled and
emptied once.
The magnetic field influences a reed sensor arranged outside of the FMC housing,
which closes a contact as soon as a certain field strength is reached, thereby making
it possible to achieve a contactless transfer from the inside of the measuring unit to the
outside.
The central arrangement of the sensor results in the contact being closed after every
half revolution of the magnet and thus the pulses stop when the measuring chamber
is half full (0.05 l/pulse with FMC and 0.125 l/pulse with FMC 250).
