Okla. Admin. Code § 165:15-15-54

Current through Vol. 42, No. 7, December 16, 2024

Section 165:15-15-54 - Wholesale devices

(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.
