7.4 Determination of Relative Density The relative density of the Gas delivered hereunder shall be determined at TransGas' option, either: (a) by a recording Gas gravitometer installed, operated and maintained by TransGas in which case the arithmetic average of readings recorded each Day shall be deemed to be the relative density of, and shall be used in computing the volume of Gas delivered during such Day, or (b) by tests conducted by TransGas on samples of such Gas. The Gas samples to be tested may be either spot samples or continuous samples, but shall be taken in such a manner and at such times to ensure that the samples taken and tested are representative of the Gas delivered hereunder. Tests shall be concurrent with the measurement of the Gas delivered or if only one such test be made during a particular Month, the figure resulting from such test shall have effect upon the first Day of the Month next succeeding the Month in which such test was made, or if more than one such test be made during a particular Month, the results of such tests shall be averaged to the nearest one one-thousandth (.001) and the resulting figure shall likewise have effect upon the first Day of the Month next succeeding the Month in which such tests were made, PROVIDED that the figure resulting from the first test or tests made during the first Month shall also have effect during the first Month. Upon a figure having effect, the same shall remain in force and effect until the effective date of the next succeeding figure and each figure, during the period in which it has effect, shall be deemed to be the relative density of all Gas delivered during such period. 7.5 Determination of Temperature and Pressure The flowing temperature and pressure of the Gas shall be determined by means of a temperature and pressure recorder approved in accordance with Clause 6.3 herein. The temperature and pressure recorder shall be installed and maintained by TransGas. The average of temperature and pressure readings recorded each Day shall be used in computing the volumes of Gas delivered during such Day. 7.6 Determination of Actual Heating Value The Actual Heating Value of the Gas delivered hereunder shall be determined at TransGas' option, either by: (a) the use of a standard recording calorimeter or chromatograph installed, operated and maintained by TransGas, in which case the Actual Heating Value of the Gas delivered each Month shall be determined by weighing volumetrically the continuous Heating Values provide by the device, or
