Abstract
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, 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.degree., on each counting wheel, 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.
