# Title 64 — Weights, Measures, and Grades

## Chapter 64-04 — Standards and Weights of Liquefied Petroleum Gas

### § 64-04-01. Restrictions upon sale of liquefied petroleum gas.

It is unlawful to sell or offer for sale, either at wholesale or retail, any liquefied petroleum
gas, either in liquid or vapor form, except by avoirdupois weight, specified in pounds; liquid
measure, specified in gallons; vapor measure, specified in cubic feet; or specified in such other
units approved by the commission.
### § 64-04-02. Authority of commission to test and condemn weighing and measuring

devices.
The commission may test or calibrate weighing and measuring devices used in the retail
sale of liquefied petroleum gas, either in liquid or vapor form, and shall condemn all devices
found not to be within the permitted tolerance or which do not clearly state the quantity of
liquefied petroleum gas, either in liquid or vapor form, in pounds, gallons, cubic feet, or other
units approved by the commission. The commission shall conspicuously mark all condemned
devices, which mark may not be removed or defaced except upon authorization of the
commission.
### § 64-04-03. Specification of liquid gas meters.

All liquid gas meters must be of a positive displacement type equipped with a vapor
separator or provided with other equipment which will positively eliminate all air and vapor from
passing through the meter with the liquid gas, and a differential pressure regulator. The meters
must be corrected, prior to use, to sixty degrees Fahrenheit [15.5 degrees Celsius] liquid gas
temperature and all deliveries of liquid gas through such meters must, at the time and place of
delivery, be temperature-corrected to sixty degrees Fahrenheit [15.5 degrees Celsius] and the
customer billed accordingly. It is unlawful to make retail sales to customers except where
delivered through a fuel dispenser from any bulk delivery vehicle unless such bulk delivery
vehicle is equipped with and dispenses said liquid petroleum gas through a liquid meter as
herein provided. Liquid meters may not be equipped with a bypass around the liquid meter. The
prohibition of a bypass does not prohibit the use of an equalization line.
### § 64-04-04. Commission rules - Tolerances.

The commission may adopt rules and establish tolerances within a maximum of two percent
having the force or effect of law.
### § 64-04-05. Penalty.

Any person who violates any of the provisions of this chapter or of the commission rules is
guilty of a class B misdemeanor.
