[SOR/2005-297, s. 42(F)]
  •  (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:

  • (4) The acceptance limits of error and in-service limits of error set out in the tables to subsections (2) and (3) apply to known test quantities equal to or greater than that delivered by the meter in one minute at the maximum operating rate.

  • (5) The acceptance limits of error set out in Column II of the tables to subsections (2) and (3) apply only to tests made under controlled conditions such as bench tests and, for tests for acceptance limits of error under other conditions, the limits of error set out in Column III of those tables shall apply.

  •  (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 heavy petroleum products, such as bunker oils, foodstuffs such as syrups, liquid cattle feed, fertilizers of high specific gravities or other liquids of high 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 used to measure liquids of high viscosity:

  •  (1) Subject to subsection (7), the limits of error set out in the tables to subsections (2) to (6) apply in respect of all meters that are designed to measure liquefied gases at ambient temperatures.

  • (2) The limits of error set out in the table to this subsection apply in respect of meters of a size from 25 mm to 50 mm or one inch to two inches, when tested using the liquefied gases the meters are intended to measure and using a narrow neck metal standard of the vapour displacement type.
