PDF Format

Date: 1996-12-20
Bulletin: V-08-E (rev. 1)
Category: Volume
Supersedes: V-08-E
Document(s): W&M Regs. sections 5; W&M Act, section 8

1.    Section 5 of the Weights and Measures Regulations was recently amended to exempt registers, other than those equipped with automatic temperature, pressure or density compensators, from initial inspection as required by subsection 8(b) of the Weights and Measures Act. This revision came into force on February 8, 1990 (SOR/90-118).

2.    Consequently, a replacement register equipped with a temperature, pressure or density compensator, that is installed with a certified liquid meter, must be submitted for initial inspection as required by subsection 8(b) of the Act before being used in trade if the compensator is operational. If the compensator is not operational, an initial inspection is not required.

3.    When a register is altered to function with an automatic temperature, pressure or density compensator or when its compensator is made operational, the register shall be inspected and certified in accordance with subsection 8(b) before being returned to trade use. The altered register must be of an approved design.

4.    When a register equipped with a compensator replaces another register that is also equipped with a compensator, it shall be inspected and certified before being used in trade.

4.1    When a component part such as a temperature sensor, thermal well or an ATC board is replaced in a volume compensated register that has previously been initially inspected, a subsequent initial inspection is not required. The local district office shall be notified as required by section 41 of the Regulations.

5.    When a replacement register, without compensation capability, is incorporated in a previously inspected Terminal Automation System (TAS) that performs compensations, it does not require an initial inspection. However, if a register performs any or all the compensations, or a new TAS that performs compensations is installed, an initial inspection is required.

6.    Each region should undertake to notify local device installers and suppliers as well as regional oil companies of these requirements.

7.    This policy applies to all replacement registers in motor fuel dispensers, truck mounted meters, and loading rack meters.
