ABSTRACT:
A fullscale setting device for a magnetic flowmeter or the like receives a frequency encoded input and divides it by a mixed number having an integral part and a fractional part to produce an output. The mixed number may represent a flow rate which is taken as the fullscale setting, thereby making the fullscale setting independent of the calibration of the flowmeter.
