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

PUBLISHER'S NOTE: The publication of the full text of the material that the adopting agency has incorporated by reference in this rule would be unduly cumbersome or expensive. Therefore, the full text of that material will be made available to any interested person at both the Office of the Secretary of State and the office of the adopting agency, pursuant to section 536.031.4, RSMo. Such material will be provided at the cost established by state law.

1. (1) All liquid meters used in the sale of liquefied petroleum gas (LPG) shall be equipped with an effective vapor eliminator.
2. (2) Each vehicle tank used in the retail sale of LPG shall be equipped with a meter for measurement of LPG 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) LPG 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 meter automatically corrected for temperature, the retail sales ticket shall show the metered adjusted gallons delivered.
5. (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.
6. (6) A person, firm or corporation owning or having in its possession an LPG 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 inspection authority and give full assistance and cooperation during the testing procedure. Tickets and other records of deliveries shall be made 2 CSR 90-10

available upon request to determine that proper compliance and procedure is in effect for making deliveries to retail customers.

1. (7) When liquid meters are determined to be accurate within the tolerance limits in the current edition of the National Institute of Standards and Technology Handbook 44, the inspection authority, 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 inspection authority. 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 inspection authority within forty-eight (48) hours from the date the repairs or transfer is made.
2. (8) When a liquid meter is found to be inaccurate beyond the tolerance allowed in the current edition of the National Institute of Standards and Technology Handbook 44, after a test is made, it shall be conspicuously marked INACCURATE by the inspection authority and shall not be used for measuring liquid gallons to retail customers until it has been corrected within tolerance limits.
3. (9) Any registrant delivering a lesser amount of LPG to a retail customer than is invoiced to the customer, if it is proven at a hearing conducted 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.
