  • Solid-state pulse generator
    Patent number: 5530298
    Abstract: A solid-state pulse generator for use in determining the output of a gas volume meter. A sensor detects a change in a magnetic field with rotation of a gas meter element and generates an electrical output pulse. A MOSFET switch having output terminals is coupled to the sensor for forming a closed circuit between the output terminals when the pulse is generated by the sensor thereby enabling a data collection circuit coupled to the MOSFET output terminals.
