1. (a) On a device equipped with an automatic temperature-compensating mechanism that will record in terms of liters or gallons compensated to 60 degrees Fahrenheit, provision shall be made for deactivating the automatic temperature-compensating mechanism so that the meter can indicate, and record if it is equipped to record, in terms of the uncompensated volume.
2. (b) A device equipped with automatic temperature compensation shall indicate and record, if equipped to record, both the gross uncompensated and net compensated volume for testing purposes or, if both values cannot be displayed or recorded for the same test draft, means shall be provided to select either the gross or net indication for each test draft.
3. (c) Adequate provision shall be made for physically applying security seals in such a manner, or through the use of a data change audit trail, that an automatic temperature-compensating system cannot be disconnected and that no adjustment can be made to the system without compromising the security seal or audit trail.

4. (d) For testing purposes of an automatic temperature-compensating system means shall be provided for the determinations of the temperature of the liquid at one of the following locations:

   1. (1) In the liquid chamber of the meter; or
   2. (2) Immediately adjacent to the meter in the meter inlet or discharge line.
