SECTION 165:15-15-33. Indicators on liquid measuring devices

(a)   Symmetry. The index of an indicator must have symmetrical graduations.

(b)   Length. The index of an indicator must reach to the finest graduations with which it is used, unless the indicator and the graduations are in the same plane, in which case the distance between the end of the indicator and the ends of the graduations, measured along the line of graduations, must not be more than 0.04 inch.

(c)   Width.

(1)   The width of the index of an indicator in relation to the series of graduations with which it is used must not be greater than:

(A)   The width of the widest graduation, and

(B)   The width of the minimum clear interval between graduations.

(2)   When the index of an indicator extends along the entire length of a graduation, that portion of the index of the indicator that may be brought into coincidence with the graduation must be of the same width throughout the length of the index that coincides with the graduation.

(d)   Clearance. The clearance between the index of an indicator and the graduations must in no case be more than 0.06 inch.

(e)   Parallax. Parallax effects must be reduced to the practicable minimum.
