Weights and Measures Regulations (C.R.C., c. 1605)

Regulations are current to 2023-01-11 and last amended on 2019-06-17. Previous Versions

PART VSpecifications Relating to Devices (continued)

DIVISION XIVolumetric Liquid Meters (continued)

Design, Composition and Construction (continued)

 A meter that has a ticket printer shall be so designed that a jammed ticket can be removed without breaking the examination seals on the means of adjusting the registration.

  • SOR/90-118, s. 33
  • SOR/2014-111, s. 46

 Where an automatic temperature-compensated or other type of compensated register is installed on a meter, an uncompensated register shall also be provided that indicates the uncompensated volume measured by the meter.

 The purchaser’s cumulative register on a key-operated self-serve meter shall be designed so that it is readily visible to the purchaser at the time of delivery and will permit comparison with the quantity indication of the delivery shown by the primary indicator.

 A meter shall have a sealable means of adjustment that will permit the meter to be adjusted to within 0.05 per cent of the quantity dispensed through the meter.

  • SOR/90-118, s. 34

Performance

[
  • SOR/2005-297, s. 42(F)
]

 When a meter is tested for acceptance limits of error at any flow rate between its rated maximum flow and its rated minimum flow using a known test quantity of liquid set out in Column I of an item in the applicable table to sections 265 to 270, the meter is within the acceptance limits of error in respect of that quantity if the quantity registered by the meter does not differ from the known test quantity by an amount in excess of the amount set out in Column II of that item.

  • SOR/89-570, s. 6(F)

 When a meter is tested for in-service limits of error at any flow rate between its rated maximum flow and its rated minimum flow using a known test quantity of liquid set out in Column I of an item in the applicable table to sections 265 to 270, the meter is within the in-service limits of error in respect of that quantity if the quantity registered by the meter does not differ from the known test quantity by an amount in excess of the amount set out in Column III of that item.

  • SOR/89-570, s. 6(F)

 Where a meter is tested for acceptance limits of error or in-service limits of error using three consecutive tests conducted at any single rate of flow or at any flow rate of the same pattern that falls between its rated maximum flow and its rated minimum flow, the spread of the test results shall not exceed two fifths of the applicable limit of error for the meter.

  • SOR/89-570, s. 6(F)
  • SOR/2005-297, s. 19

 [Revoked, SOR/90-118, s. 35]

  •  (1) Subject to subsection (4), the limits of error set out in the tables to subsections (2) and (3) apply to slow-flow dispensers incorporating either meters or self-measuring pumps, dispensers for motor fuel of the service station type, meters on refuellers for small aircraft and boats, meters on vehicle tanks and to all other meters for use in measuring automotive or petroleum liquids in retail trade and that are not otherwise mentioned in the tables in this Division.

  • (2) The limits of error set out in the following table apply to meters that register in metric units of volume:

  •  (1) Subject to subsections (4) and (5), the limits of error set out in the tables to subsections (2) and (3) apply to all positive displacement bulk volumetric liquid meters, including vehicle-mounted meters, that are designed to measure volumes of 180 litres or more, or 40 gallons or more, of refined petroleum products such as gasoline and fuel oils, foodstuffs such as milk, liquid fertilizers of the solution type such as aqua ammonia, or other liquids of low viscosity.

  • (2) The limits of error set out in the following table apply to meters, generally of a size 65 mm or 2½ inches or smaller that are designed to measure liquids of low viscosity:
