Abstract: The digits of the meter are each represented by the position of a member rotatable to one of ten different positions. The positions of the members do not change simultaneously. A set of first and second sensors are provided for each member. Each sensor is effective, when actuated, to sense the position of the member associated therewith. In each set, the first and second sensors are spaced apart, along the direction of movement of the member, by a distance less than the distance between adjacent positions of the member. The first sensor in each set is actuated, in sequence, to detect the position of the corresponding member and to generate a code representative of the sensed position. The codes for the first meter reading are converted into a first number, which is stored. After a delay sufficient to permit all of the members to change position, the second sensor in each set is actuated, in sequence. Each of the second sensors generates a code representative of the position of the corresponding member.
