ABSTRACT:
A circuit for a vortex shedding flowmeter is disclosed which generates an analog signal proportional to the vortex shedding frequency and a pulse signal which equals or is proportional to the vortex shedding frequency signal. A scaling or range selection counter can be provided between the pulse signal and an output stage for changing the effective range of measurement by dividing the shedding frequency by a selected and known number.
