However, such corrections or conversions must be performed using proper and prescribed methods in order to ensure an accurate statement of the net quantity.

The purpose of revision 2 was to set a date after which the practise of manual temperature compensation will not be allowed. P E is “0” for liquids which have an equilibrium vapour pressure less than It shall also state the reference density used, the mean temperature, the gross meter registration and the calculated net quantity.

For additional information regarding this bulletin, please contact the Senior Program Officer responsible for volume. It shall also state the reference pressure used, the reference density used, the mean temperature, mean pressure as well as the net and gross meter registrations. In situations where pressure compensation is desirable, additional dynamic pressure sensing elements must be provided in the metering installation.

Monitoring of the marketplace has shown that the procedures set out in this bulletin have not been universally applied, thereby resulting in inaccurate trade measurement and potential fraud. This table is either as prescribed in section of the Weights and Measures Regulations or in the appropriate bulletin.

If the temperature is to be manually determined, the contents of section 3 of this bulletin apply. V—Manual correction of measured liquid volumes xhapter equivalent volumes at reference conditions Category: The purpose of revision 3 was to update the format of the bulletin to meet web accessibility requirements. Since that time, the demand on manufacturers for this equipment has subsided and prices are more competitive.


If needed, interpolate the VCF value to the nearest 0. These tables are summarized in Table 1. Correction factors for the effect of pressure C pl on propane liquid volume Source: Read tale VCF corresponding to the mean liquid temperature.

This bulletin communicates the policy and outlines the procedures for the manual correction of measured liquid volumes to equivalent volumes at reference conditions. Please refer to the applicable bulletin for tables approved for specific non petroleum-based products. For these reasons, the practice of manual temperature compensation, at all levels of trade, will not be permitted after January 1,
