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

232. In this Division, “machine” means a volumetric liquid measuring machine and includes a volumetric liquid meter or a measuring tank for use in trade.

233. A machine shall be designed and constructed to ensure complete delivery of the measured liquid and to prevent delivery of any unmeasured liquid.

234. All movable capacity indicators and means of adjustment on a machine shall be sealable.

• 235. (1) Component parts of a machine the removal or alteration of which could have an effect on the accuracy of measurement of the machine shall be sealable.

• (2) Subsection (1) does not apply to a meter designed for measuring liquid food commodities.

236. Except as otherwise authorized by specifications established by the Minister, a machine shall register in units of volume of liquid at the temperature and pressure of the liquid in the measuring element of the machine.

237. A machine may be tested and calibrated using a liquid other than the liquid that the machine will measure in trade if the test liquid has hydraulic properties similar to the liquid that the machine will measure in trade or the test liquid is used with a correction factor that has been specified by the Minister.

238. Where a machine is incorporated into a measuring system, the component parts of the system, including the liquid supply tank and any pump, piping, valve or delivery hose, shall be installed and used so as not to cause the machine to cease to measure accurately.

239. Unless otherwise authorized by specifications established by the Minister, a machine shall be installed so as to prevent the inter-mixing of liquids therein unless it is a machine approved for that purpose.

240. When a machine is installed in conjunction with piping other than a delivery hose or a short jumper hose, the piping shall be of rigid material.

241. In this Division,

“meter”

“meter” means a volumetric liquid measuring machine for use in trade that is of the meter type or incorporates a meter; (compteur)

“registration”

“registration” includes both visual indication and recorded representation of volume, unit price or monetary value. (enregistrement)

242. The rated maximum flow of a meter shall be such that, when it is tested using refined petroleum products with normal lubricating properties such as kerosene or fuel oil, the meter will measure accurately without abnormal wear, and the meter shall be de-rated if necessary for use on products with lesser lubricating properties.

• 243. (1) The rated minimum flow of a meter designed to measure liquids other than liquefied gases shall be 20 per cent or less of the rated maximum flow of the meter.

• (2) Subject to subsection (3), the rated minimum flow of a meter designed to measure liquefied gases shall be 33 per cent or less of the rated maximum flow of the meter.

• (3) The rated minimum flow of a meter with a rated maximum flow of 90 L or less per minute that is designed to measure liquefied gases and to dispense liquefied gases to motor vehicles shall be 13 L or less per minute.
