Abstract:
    The present invention discloses a multidigit counting wheel mechanism for a volume-measuring instrument. An absolute encoder for a measuring instrument includes a mechanical counting wheel mechanism consisting of five sensors(20), mounted in a plane perpendicular to a counting mechanism axle, for each counting wheel and a code, producing a digital rotary angle signal with a resolution of 12 DEG , on each counting wheel(21), with the counting wheel mechanism being visually readable in a conventional manner, with the encoder not increasing the torque required for driving the counting mechanism.
