When liquefied petroleum gas is sold or delivered to a consumer as a liquid and by liquid measurement, the volume of liquid sold and delivered must be corrected to a temperature of 60 degrees Fahrenheit through the use of the volume correction table, shown in part 7601.9900, and calculated under subpart 2, or through use of an approved meter with a sealed automatic compensating mechanism. A sale ticket must show the delivered gallons, the temperature at the time of delivery, and the corrected gallonage, or must state that temperature correction was automatically made.

This part does not apply to unit sales or deliveries made directly to mobile fuel tanks with a capacity of less than 100 gallons.

Subp. 2.

Calculation.

To convert from measured volume at another temperature to net volume at 60 degrees Fahrenheit: measure the volume and temperature, determine the specific gravity at 60 degrees Fahrenheit, refer to the column in the volume conversion table, set forth in part 7601.9900, corresponding to the specific gravity, and read the volume conversion factor opposite the observed temperature. Multiply the observed volume by this factor to obtain the volume at 60 degrees Fahrenheit.

VOLUNTARY PLACING IN SERVICE PROGRAM

7601.7000 PLACING IN SERVICE PROGRAM; PURPOSE AND POLICY.

Subpart 1.

Registered persons.

The director shall offer a voluntary registration program for persons who install, adjust, repair, service, or test commercial weighing and measuring equipment. The purposes of the program are to:

A.

allow privately employed individuals to place newly installed or repaired weighing and measuring equipment into commercial service, pending an inspection by the division; and

B.

minimize the compliance burden on owners and operators of weighing and measuring equipment by simplifying installation and repair and by reducing the amount of time the equipment is out of service.

Subp. 2.

Nonregistered persons.

A nonregistered person is not prohibited from repairing commercial weighing and measuring equipment. However, Minnesota Statutes, chapter 239, prohibits commercial use of equipment that has been repaired by a nonregistered person until the equipment has been approved by the division.
