 A measuring tank shall not be used for deliveries of quantities between internal capacity indicators.

  • SOR/2014-111, s. 45.

 A vehicle tank not equipped with level gauges shall, when being used to measure, be on a surface that is within three degrees of level.

 A vehicle tank that is equipped with level gauges shall, when being used to measure, be level within the limits marked on the level gauges.
