Registers and Pulse Generators

Contact-Closure Pulse Genertors

       This pulse generator is designed to mount on an OVAL flowmeter. The flowmeter's rotor revolution proportional to the rate of flow is transmitted through a conversion gear train to a permanent magnet which in turn drives a reed switch, whereby a contact-closure pulse train proportional to the flow rate is generated. This pulse generator is used only factored pulse generation.
