288. Where it is necessary
(a) to limit changes in the viscosity of, or the solubility of material dissolved in, the liquid to be measured by the meter, or
(b) to limit the rate of change of the temperature or pressure of the liquid to be measured by the meter when the meter is equipped with an automatic compensator,
appropriate automatic controls shall be installed in the meter system to permit the meter to measure accurately.
- SOR/90-118, s. 39.
289. (1) The piping on the downstream side of meters may be concealed and the outlets interconnected where the meters
(a) are used
(i) at pipeline terminals, or
(ii) exclusively for loading or unloading railway tank cars or loading or unloading tanker ships; and
(b) have adequately interlocked manual or automatic valves with means for leakage detection incorporated in the meter systems to prevent the diversion of measured liquid.
(2) The piping on the downstream side of the meters may be concealed where the meters have more than one outlet and are used exclusively for refuelling trucks.
- SOR/2005-297, s. 21.
290. A meter shall be operated only at flow rates between the rated minimum and maximum flow rates marked on the name plate of the meter.
291. If any part of a meter system is drained for any reason the entire system shall be re-primed and re-filled and the register set to zero before the meter is used for the next measurement.
292. A flow transmitter for input to an electronic data processing system may be attached to a liquid meter and the output from the data processing system used for invoicing purposes if the purchaser of the liquid being measured or his agent is given a printed copy of the data recorded by the data processing system before he leaves the trader’s premises.
293. A flow transmitter may be installed at a key-operated self-service meter installation to drive the unverified accumulative totalizers for individual customers if the purchaser of the liquid being measured is able to visually check the advance of his totalizer against the indication of the primary indicator at the time of delivery of the liquid.
294. Where a meter mounted on a vehicle tank is used in circumstances where the purchaser does not normally view the meter during delivery of a liquid, the meter shall be equipped with an interlocked ticket printer that shall be used for each delivery of the liquid.
295. Tickets used with a meter equipped with an automatic temperature or other compensator shall bear statements that the volume indicated thereon has been adjusted to correspond to an equivalent volume at a standard condition stated on the ticket.
