PURPOSE: This rule sets out minimum general standards governing the design of meters used for measuring liquefied petroleum gas.

PUBLISHER’S NOTE: The secretary of state has determined that the publication of the entire text of the material which is incorporated by reference as a portion of this rule would be unduly cumbersome or expensive. This material as incorporated by reference in this rule shall be maintained by the agency at its headquarters and shall be made available to the public for inspection and copying at no more than the actual cost of reproduction. This note applies only to the reference material. The entire text of the rule is printed here.

1. (1) All liquid meters used in the sale of liquefied petroleum gas (LP gas) shall be equipped with an effective vapor eliminator.
2. (2) Each vehicle tank used in the retail sale of LP gas shall be equipped with a meter for measurement of LP gas in terms of gallons and shall not be equipped with a bypass around the meter. A vapor equalization line is not a bypass and is not prohibited by this provision.
3. (3) LP gas sold or delivered to a retail customer by liquid measure shall be corrected for temperature to sixty degrees Fahrenheit (60 °F) with an automatic correction device or the quantity delivered shall be corrected for temperature of sixty degrees Fahrenheit (60 °F) in accordance with the Volume Correction Factor Table, nationally accepted as accurate within fair tolerances.
4. (4) When the delivery is made through a 2 CSR 90-10

meter automatically corrected for temperature, the retail sales ticket shall show the metered adjusted gallons delivered.

1. (5) When the delivery is made through a meter not corrected automatically, the retail sales ticket shall show the metered gallons delivered, the temperature at the time of delivery and the corrected gallonage.
2. (6) A person, firm, or corporation owning or having in its possession an LP gas measuring device which is installed for use to measure liquid gallons to a retail customer in this state shall permit the device to be tested after reasonable request is made by the director of the Department of Agriculture and give full assistance and cooperation during the testing procedure. Tickets and other records of deliveries shall be made available upon request to determine that proper compliance and procedure is in effect for making deliveries to retail customers.
3. (7) When liquid meters are determined to be accurate within the tolerance limits in the 2008 edition of the National Institute of Standards and Technology Handbook 44, published by the National Institute of Standards and Technology, Weights and Measures Division, 100 Bureau Dr., Stop 2600, Gaithersburg, MD 20899-2600 and incorporated by reference, the director of the Department of Agriculture, immediately upon completion of the test, shall seal the meter in a manner so as to prevent tampering which would affect the accuracy of measurement. No person shall remove, break, or tamper with the meter seal without the written consent of the director of the Department of Agriculture. These requirements shall not preclude the necessity to make needed repairs to the metering device or to transfer to another tank. If it is necessary to break or remove the seal to accomplish repairs or transfer, written notice shall be given to the director of the Department of Agriculture within forty-eight (48) hours from the date the repairs or transfer is made. This rule does not incorporate any subsequent amendments or additions to the referenced material.
4. (8) When a liquid meter is found to be inaccurate beyond the tolerance allowed in the National Institute of Standards and Technology Handbook 44, after a test is made, it shall be conspicuously marked INACCURATE by the director of the Department of Agriculture and shall not be used for measuring liquid gallons to retail customers until it has been corrected within tolerance limits.
5. (9) Any registrant delivering a lesser amount of LP gas to a retail customer than is invoiced to the customer, if it is proven at a hearing conducted by the director of the Department of Agriculture for this purpose that the shortage of delivery and overbilling of the amount delivered was made with intent to defraud, shall be subject to having his/her registration permit suspended by the inspection authority.
