  VCF

  VCF  means, in respect of a mechanical or electronic automatic temperature compensator, the applicable volume correction factor

  • (a) at the temperature of the measured liquid during each test of the compensator, in the column corresponding to the density at 15°C in kilograms per cubic metre for which the compensator is marked or adjusted, or to the density corresponding to the cubical coefficient of thermal expansion, relative density or API gravity for which the compensator is marked or adjusted, that is set out

  • (b) at the temperature of the measured liquid during each test of the compensator, in the column corresponding to the agreed or experimentally determined cubical coefficient of thermal expansion at 15°C for that liquid and for which the compensator is marked or adjusted, that is set out, in the case of special petroleum liquids to which Tables 54A, 54B and 54D of the API Standard are not applicable, in Table 54C of the API Standard, or

  • (c) at the temperature of the measured liquid during each test of the compensator, in the column corresponding to the density at 15°C in grams per litre for which the compensator is marked or adjusted, or to the density corresponding to the cubical coefficient of thermal expansion, relative density or API gravity for which the compensator is marked or adjusted, that is set out, in the case of liquefied petroleum gases, natural gas liquids and asphalts, in Table 54 of the ASTM-IP Petroleum Measurement Tables, with designation ASTM D1250, 1953 Metric Edition. (FCV)

• 178 (1) An electronic machine shall perform within the applicable limits of error, when tested after being calibrated and zeroed, under relative humidity conditions between 10 per cent and 95 per cent, and under one of the following operating conditions:

  • (a) the ambient temperature range is -10°C to +40°C, unless expressly specified otherwise on the approval application and marked on the machine;

  • (b) if the specified minimum temperature is lower than -10°C or the specified maximum temperature is more than +40°C, the machine shall bear markings specifying the minimum and maximum temperatures and shall be approved for use within this expanded temperature range, if Measurement Canada laboratories are equipped to test at those temperatures;

  • (c) when a machine meets the conditions described in paragraphs (a) and (b), it may be used beyond the approved minimum and maximum temperatures if it continues to perform within allowable limits of error; or

  • (d) if the specified minimum temperature is higher than -10°C or the specified maximum temperature is less than +40°C, the machine shall bear markings specifying the minimum and maximum temperatures and shall only be approved for use within this reduced temperature range.
