## PART VIIFunctions of an Inspector

**32** The functions of an inspector shall be the carrying out of

(a) any inspection and testing of meters and any inspection of their installation required for the purposes of the Act and these Regulations;

(b) any inspection and testing required to enable the determination of a period for the purposes of paragraph 12(1)(c) of the Act;

(c) any accreditation audit referred to in section 24 or any audit required pursuant to a condition referred to in section 25;

(d) any investigation required to assist in the determination of whether there is or has been an offence under section 30 of the Act;

(e) any investigations, tests, inquiries and examinations in relation to sections 9, 11 and 23 of the Act; and

(f) such other functions as are reasonably ancillary to the functions listed in paragraphs (a) to (e).

**33** An inspector shall not, in the execution of his functions, use any measuring apparatus other than a measuring apparatus permitted by section 5 of the Act.

## PART VIIIProvisions Specific to Gas

### Prohibited Substances

**34** No person shall supply to a purchaser for any purpose other than processing or delivery for processing, natural gas that contains more than 0.030 per cent of water vapour, calculated by volume at standard pressure and standard temperature.

### Sale of Gas by Volume

**35** A volume of gas measured by any meter that registers in units of volume shall be converted to standard volume by using the following equation, namely,

V_{s} = V_{r} × P_{m} × T_{m} × (F_{pv})^{2}

where

(a) V

_{s}is the standard volume;(b) V

_{r}is the volume registered by the meter;(c) P

_{m}is the pressure multiplier established for the meter pursuant to section 36;(d) T

_{m}is the temperature multiplier established for the meter pursuant to section 38 or 39, whichever is applicable; and(e) F

_{pv}is the supercompressibility factor established for the meter pursuant to section 40.

- SOR/95-532, s. 3(F)

### Pressure Multiplier

**36**(1) The pressure multiplier for any pressure converting meter shall be established by using the following equation, namely,(2) The pressure multiplier for any meter other than a pressure correcting meter shall be established by using the following equation, namely,

P

_{m}= (P_{ga}+ P_{a})/P_{s}where

(a) P

_{m}is the pressure multiplier;(b) P

_{ga}is the average meter pressure expressed on the gauge pressure scale;(c) P

_{a}is(i) the mean atmospheric pressure at the meter location, expressed to at least four significant digits,

(ii) the atmospheric pressure calculated for the meter location pursuant to subsection 37(1), expressed to at least four significant digits,

(iii) the atmospheric pressure declared for the meter location pursuant to subsection 37(2), expressed to at least four significant digits, or

(iv) the measured atmospheric pressure at the meter location, expressed to at least four significant digits; and

(d) P

_{s}is the standard pressure expressed on the absolute pressure scale.

- SOR/95-532, s. 3

### Atmospheric Pressure

**37**(1) The atmospheric pressure shall be calculated for a meter location by using the following equation, namely,(a) in the International system of units,

P

_{a}= 101.560 - (0.0113 × M) kPa, or(b) in the Imperial system of units,

P

_{a}= 14.73 - (0.0005 × F) psiawhere

(c) P

_{a}is the calculated atmospheric pressure; and(d) M is the number of metres of elevation of the meter location above mean sea level and F is the number of feet of elevation of the meter location above mean sea level, in either case as determined by a survey carried out by a registered surveyor or as determined from the most recent applicable topographical maps published by the Department of Energy, Mines and Resources.

(2) The atmospheric pressure declared for a meter location shall not differ from the atmospheric pressure calculated for that meter location pursuant to subsection (1) by more than

### Temperature Multiplier

**38**(1) Subject to section 39, the temperature multiplier for any temperature converting meter shall be established by using the following equation, namely,(a) in the International system of units,

T

_{m}= 288.15/(T_{b}+ 273.15), or(b) in the Imperial system of units,

T

_{m}= 519.67/(T_{b}+ 459.67)where

(c) T

_{m}is the temperature multiplier; and(d) T

_{b}is the temperature established by the contractor and used as the base temperature for the calibration of the temperature converting meter.

(2) Subject to section 39, the temperature multiplier of any meter other than a temperature converting meter shall be established by using the following equation, namely,

- SOR/95-532, s. 3

**39** A temperature multiplier of one may be used for

(a) meters that are purchased prior to December 31, 1986 and

(b) meters that are installed prior to December 31, 1986, where the average meter pressure exceeds the atmospheric pressure by more than 3.5 kPa in the International system of units or 0.5 psi in the Imperial system of units; and

(c) meters that are installed where the average meter pressure does not exceed the atmospheric pressure by more than 3.5 kPa in the International system of units or 0.5 psi in the Imperial system of units and that
