1. A metering system for forming a net output comprising:

  • a. meter means for producing a meter signal functionally related to the value of a monitored, variable value parameter;

    b. measuring means connected with said meter signal for forming a net output signal each time said meter signal provides a predetermined input to said measuring means;

    c. selector means included with said measuring means for selecting the value of said meter signal required to form a net output signal, said selector means including a factor control setting means which may be set at a value equal to the meter signal value desired for forming a net output signal;

    d. register means supplied with said net output signal for accumulating a count of said net output signals, e. ticket printing means included with said register means for selectively printing the accumulated register count of net output signals in said register means onto a recording medium;

    f. power means connected with said register means for supplying power for mechanically advancing the count of said register means and for imprinting the register count onto said recording medium;

    g. feedback control means connected with said power means for causing said power means to advance said register count when said net output signals are supplied to said control means and for causing said power means to stop advancing said register count when the accumulated count in said register has advanced by a preselected amount;

    h. an incremental electrical motor included in said power means, said electrical motor having a rotor adapted to rotate one angular increment for each pulse of a pulsating electrical power supply applied to said motor;

    i. a rotatable drive shaft included in said register means for mechanically driving said printing means and for advancing said register count by an amount related to the angular position of said drive shaft, said motor being mechanically connected with the rotor of said drive shaft to rotate said shaft when said rotor is rotated;

    j. sensing means included in said control means for forming a sensing feedback signal indicating the angular position of said drive shaft; and

    k. switching means further included in said control means for applying said pulsating power supply to said motor in response to the formation of net output signals by said measuring means and for removing said pulsating power supply from said motor when said sensing feedback signal indicates that said drive shaft is at a predetermined angular position.
