Current through Vol. 41, No. 20, July 1, 2024
(a)
				  Wholesale devices must be calibrated by a certified source. The result must be
				  mailed to the Compliance and Inspection Department with a pass or fail rating.
				  Upon receipt of documentation, a Fuel Specialist from the Compliance and
				  Inspection Department will deliver a sticker on the next routine visit.
(b) These guidelines are required
				  for wholesale meter calibrations:
(1)
Discharge rates.
A wholesale measuring device must be marked to
				  show its designed maximum and minimum discharge rates. However, such minimum
				  discharge rates must not exceed 20 percent of such maximum discharge
				  rates.
(2)
Temperature
				  compensation.
If a measuring device is equipped with an automatic
				  temperature compensator, the primary indicating elements, recording elements
				  and recorded representation must be clearly and conspicuously marked to show
				  that the volume delivered has been adjusted to the volume at
				  60°F.
(3)
Test
				  liquid.
A liquid measuring device must be tested with the liquid to be
				  commercially measured or with a liquid of the same general physical
				  characteristics.
(4)
Evaporation and volume change.
Care must be exercised to minimize
				  evaporation losses and volume changes resulting from changes in temperature of
				  the test liquid.
(5)
Normal
				  tests.
The "normal" test of a measuring device must be made at the
				  maximum discharge rate that may be anticipated under the conditions of
				  installation. If a wholesale device is equipped with an automatic temperature
				  compensator, this test should be conducted with the temperature compensator
				  deactivated.
(6)
Automatic
				  temperature compensation on wholesale devices.
If a measuring device is
				  equipped with an automatic temperature compensator, it must be tested by
				  comparing the volume indicated or recorded by the device with the compensator
				  connected and operating, with the actual delivered volume corrected to
				  60°F.
(7)
Temperature
				  correction on wholesale devices.
Corrections must be made for any
				  changes in volume resulting from the differences in liquid temperatures between
				  time of passage through the meter and time of volumetric determination in the
				  test measure. When adjustments are necessary, appropriate petroleum measurement
				  tables should be used. The temperature used to make the volumetric adjustment
				  must be recorded on the invoice.
(8)
Sticker and seal.
Upon
				  receipt of documentation of calibration, a Fuel Specialist will place a
				  Commission sticker upon the meter. The Fuel Specialist will ensure that the
				  meter is sealed, so that entry to the meter is prevented. At the time the seal
				  is broken, the Compliance and Inspection Department must be notified within one
				  (1) day and recalibration must be completed within ten (10) days. If after ten
				  (10) days recalibration is not completed, that device must be taken out of
				  service until calibration is completed.
