  • Mass flowmeter starting system
    Patent number: 3994165
    Abstract: A Zener diode voltage sensing circuit senses when the 115 volt, 400 Hz primary power source to a conventional 8 Hz two-phase mass flowmeter is below approximately 80 volts and through an amplifier, a frequency halving flip-flop, and a quad NAND gate halves the frequency from 8 Hz to 4 Hz so that the impeller of the two-phase drive motor will start or continue rotating, then as the primary voltage rises above the 80 volt predetermined amount, and after approximately a one-second delay, the 4 Hz, two-phase drive frequency is changed to the normal two-phase 8 Hz impeller driver voltage.
