Okla. Admin. Code § 165:15-15-31

Current through Vol. 42, No. 4, November 1, 2024

Section 165:15-15-31 - Primary elements

(a)General. A liquid measuring device must be equipped with a primary indicating element and may also be equipped with a primary recording element.

(b)Units. A liquid measuring device must be equipped to record its deliveries in terms of gallons, liter, or decimal subdivisions of the gallon or liter.

(c)Value of smallest unit. The value of the smallest unit of indicated delivery, and recorded delivery if the device is equipped to record, must not exceed:

(1) One thousandth (.001) gallon or two thousandth (.002) liter on digital type retail devices, or one-tenth (0.1) gallon or one-tenth (0.1) liter on analog type systems.

(2) One gallon or one liter on wholesale devices.

(d)Return to zero. Primary indicating and recording elements must advance only by the mechanical or electronic operation of the measuring device. However, a measuring device may be cleared by advancing its elements to zero, but only if:

(1) The advancing movement, once started, cannot be stopped until zero is reached; or

(2) In the case of indicating elements only, such elements are automatically obscured until the elements reach the correct zero position.

(e)Return to zero (key-lock). The primary indicating elements, and primary recording elements if the device is equipped to record, must be readily returnable to a definite zero indication. However, a key-lock or other self-operated device may be equipped with cumulative indicating or recording elements, provided that it is also equipped with a zero-return indicating element. Means must be provided to prevent the return of primary indicating elements, and of primary recording elements if the device is so equipped, beyond their correct zero position.
