FAM3200 ARMORED VARIABLE AREA PURGEMETER | CI/FAM3200-EN REV. D
2 Functional description
The flowmeters in the FAM3200 work according to the float
principle.
The position of the float in the conical meter tube is proportional
to the flow.
A magnet in the float translates the height of the float as a
measurement for the flow to the decouple-proof magnet
follower system of the flowmeter.
The flow rate value is indicated on a scale by a pointer mounted
on a rotating shaft.
