接点パルス発信器_容積流量計

接点パルス発信器_容積流量計

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 for factored pulse generation.
